Voltage Protector Price in Pakistan 2026 — Complete Buying Guide
Voltage Protector Price in Pakistan 2026 — Complete Buying Guide
Updated June 2026 | By CNC Electric Pakistan | 11 min read
Pakistan’s WAPDA and K-Electric grids regularly swing between 140V and 280V—far outside the 220V ±5% that household appliances are designed for. A single over-voltage spike after load-shedding ends can fry an inverter AC compressor worth PKR 80,000 in under a second; persistent under-voltage burns motor windings in fridges and water pumps over weeks. A voltage protector (also called a VA protector, voltage protection device, or under/over voltage relay) is a DIN-rail device that automatically disconnects the supply when voltage leaves a safe window and reconnects when it stabilises. This guide breaks down voltage protector price in Pakistan for 2026, sizing rules, and how to choose between single-phase and 3-phase, mechanical relay vs digital LED display.
Voltage Protector Price Pakistan 2026 — Quick Answer
- 40A single-phase digital voltage protector: PKR 1,800 – 3,200
- 63A single-phase digital voltage protector: PKR 2,400 – 4,500
- 80A single-phase voltage protector (heavy load): PKR 3,800 – 6,200
- 3-phase voltage protector (with phase-sequence + phase-fail): PKR 4,500 – 8,500
- 3-phase voltage protector with current monitoring: PKR 9,500 – 16,000
- WiFi smart voltage protector (Tuya app): PKR 6,500 – 12,500
CNC Electric voltage protectors sit at the lower end of each band; imported equivalents (Schneider, Tomzn, Mitsubishi) typically run 40–90% higher for the same rating.
What Is a Voltage Protector and How Does It Work?
A voltage protector continuously monitors incoming AC voltage and switches an internal relay (or contactor) based on two thresholds:
- Over-voltage threshold: typically factory-set at 265–275V. When grid voltage rises above this limit, the protector’s relay opens and cuts power to the connected load within 1–2 seconds.
- Under-voltage threshold: typically 170–185V. Below this, the protector disconnects to prevent motors from drawing excessive current (a stalled fridge compressor at 160V can pull 4× rated current).
- Reconnection delay: 10 seconds to 6 minutes (user-adjustable on digital models). This prevents rapid on/off cycling during a marginal grid event and gives the upstream transformer time to stabilise.
Voltage protectors differ from stabilisers (which regulate the voltage to within range) and SPDs (which clamp transient surges from lightning). All three serve different threats. Detailed comparison in our SPD vs stabiliser vs voltage protector guide.

How Voltage Protector Prices Vary by Specification
1. Current Rating (Amperage)
Current rating determines how much load the protector’s internal contactor can carry. A 40A unit handles ~9 kW continuous single-phase load (220V); a 63A unit handles ~14 kW; an 80A handles ~17.5 kW. The contactor is the costliest internal component — doubling the rating roughly doubles the price. Sizing rule: pick at least 1.25× your measured peak current, or use 63A for any "whole-house" application up to 5-ton AC + standard kitchen + lighting.
2. Number of Phases (Single vs 3-Phase)
Single-phase protectors monitor one live line. 3-phase units monitor all three lives, plus phase sequence (L1-L2-L3 order matters for motors) and phase failure (loss of any one phase). A 3-phase protector is 2.5–3.5× the price of an equivalent single-phase because the controller PCB is more complex and the contactor must switch three poles simultaneously. Single-phase homes never need a 3-phase unit; 3-phase homes / commercial loads always do.
3. Display Type (LED Indicator vs Digital Voltage Display)
Cheap voltage protectors use a 3-LED indicator (Under / Normal / Over). Digital-display units show actual voltage in volts plus current draw on a 7-segment display. Digital adds PKR 800–1,500 to the price but lets the user verify the threshold settings and diagnose grid behaviour. For installations where the user is technically literate, digital pays for itself in faster fault diagnosis.
4. WiFi / Smart Connectivity
WiFi-enabled voltage protectors (CNC YCSi series, Tomzn TOMPD-63-LW) connect to the Tuya / Smart Life app. The app shows live voltage and current, logs disconnect events, allows remote on/off, and pushes notification on each over-voltage trip. Adds PKR 4,000–6,000 over equivalent non-WiFi model. Strong fit for offices and absentee-owner homes; less critical when the panel is in everyday sight.
5. Brand
Three tiers in the Pakistan voltage-protector market:
- Premium import (Schneider, ABB): PKR 8,000+ for 63A single-phase; rarely stocked, mostly project-specific orders.
- Mid-tier import (Chint, Tomzn, Delixi): PKR 3,500–6,000 for 63A single-phase. Good quality, larger retail presence.
- Value tier (CNC, Geya, generic Hall Road): PKR 1,800–3,500 for 63A. CNC carries PSQCA certification and 1-year warranty; generic Hall Road units do not.
Top 5 Best-Value Voltage Protectors in Pakistan 2026
- CNC YCVP-63 Digital — PKR 2,450. The default 5–7 kW home pick. 63A single-phase, digital voltage display, adjustable over/under thresholds (180–270V), 10–180 sec reconnect delay. Protects fridge, ACs, inverter, water motor.
- CNC YCVP-40 Compact — PKR 1,850. Best-value entry point. 40A handles a single AC + fridge + lighting (apartment use). DIN-rail mount, 2-module wide.
- CNC YCVP-3P-63 3-Phase — PKR 4,850. 3-phase 63A with phase-sequence and phase-fail detection. Protects 3-phase motors, AC unitary plant, industrial pumps. Critical for any 3-phase load — phase loss causes single-phasing burnout.
- CNC YCSi-VP-63 WiFi — PKR 6,500. Tuya-app integration: live voltage / current, trip-event history, remote on/off, push notifications. Use case: offices and shops where staff can react to alarms from phone.
- Tomzn TOMPD-63-LW WiFi + Current — PKR 8,500. Premium-tier WiFi protector with kWh metering. Good for solar-tied loads where current monitoring matters. CNC stocks this as a parallel SKU for customers who prefer Tomzn branding.
How to Spot Counterfeit Voltage Protectors in Pakistan
Counterfeit voltage protectors are common in unbranded Hall Road / Saddar / Jodia Bazaar walk-ins. Indicators:
- No PSQCA mark or printed-not-embossed fake PSQCA. Real CNC YCVP units carry the embossed "P" mark on the front bezel.
- No IEC reference on the nameplate. Genuine units reference IEC 60947-4-1 (contactor) and IEC 61810-1 (relay) standards.
- Threshold knobs that "feel" loose or have no detents. Genuine adjustment dials have a clear click between settings.
- Internal relay rated lower than nameplate. If a "63A" unit has a 25A relay inside (visible through the vent), it’s a fake — it’ll burn out at half rated load.
- No 1-year warranty card. CNC ships with a stamped warranty card; counterfeit shipments don’t.
Voltage Protector Installation Tips from Pakistani Electricians
- Install on the supply side of the DB, after the meter and main MCB. One whole-house protector is more cost-effective than per-appliance plug-in units.
- Don’t install before the MCB. Short-circuit fault current must trip the MCB first; routing it through the protector’s internal contactor risks contact welding.
- Tighten lugs to 3–4 N·m on 63A models. Under-tight terminals cause hot-spot failure; cracked terminals invite arc-tracking inside the housing.
- Set thresholds based on local grid behaviour. Default 270V over / 180V under is fine for most urban areas. In K-Electric coastal zones with chronic low voltage, drop the under-threshold to 170V or appliances will reset all day.
- Use 6–10 mm² cable for a 63A protector — never the 4 mm² that ampacity charts technically allow. Thicker cable handles inrush and reduces voltage drop.
Voltage Protector vs Stabiliser vs SPD — When to Use Which
| Threat | Right Device | Why |
|---|---|---|
| Lightning / utility transient (< 1ms surge) | SPD (Surge Protection Device) | SPDs clamp surge in microseconds; protectors are too slow |
| Sustained over-voltage (260–290V for seconds) | Voltage protector | Disconnects load entirely; SPD wouldn’t trip |
| Sustained under-voltage (160–200V) | Voltage protector | Stabiliser can boost, but disconnect is safer for motors |
| Constant low/high voltage where loads must run anyway | Servo or relay-type stabiliser | Stabiliser regulates voltage in real-time |
| 3-phase phase loss / wrong sequence | 3-phase voltage protector + phase-sequence relay | Prevents motor single-phasing burnout |
Most Pakistani homes need both an SPD (at the main DB) and a voltage protector (after the main MCB). Combined cost is typically PKR 5,000–8,000 and protects a household worth of appliances.
Bulk and Dealer Pricing
CNC Electric operates three voltage-protector pricing tiers:
- Retail (single unit): list prices above, walk-in via cncelectric.pk or authorised dealers.

WhatsApp +92 326 1111 376 or email sales@cncelectric.pk for project BoQ pricing. Solar installers and DB-panel assemblers should ask about the rebated-bundle pricing when combined with SPD + breaker orders.
Voltage Protector Compatibility With Your DB Box
- DIN-rail mount. All CNC YCVP and YCSi-VP units snap onto standard 35mm DIN-rail. 1Ph 63A protectors occupy 2 modules; 3Ph units occupy 4–5 modules.
- Space planning. A 12-way DB box has room for: 1 incoming MCB + 1 voltage protector + 1 SPD + 9 outgoing MCBs. Add a separate 4-way enclosure if you need RCBO + voltage protector together.
- Cable management. Voltage protectors are series-connected (load passes through), unlike SPDs which are parallel. Ensure incoming and outgoing terminals are clearly marked — reversing them defeats the protection. Detailed wiring at our DB box wiring guide.
Frequently Asked Questions
What is the price of a voltage protector in Pakistan 2026?
A 40A single-phase digital voltage protector starts at PKR 1,850 (CNC YCVP-40). The 63A version (most-common home pick) is PKR 2,450. Three-phase 63A with phase-sequence detection is PKR 4,850. WiFi smart voltage protectors start at PKR 6,500.
Do I need a voltage protector if I already have a stabiliser?
If your stabiliser has built-in disconnect at >270V and <170V, a separate voltage protector is optional. Many cheap relay-type stabilisers do NOT have full disconnect — they keep boosting / bucking even at 290V output. A voltage protector on the supply side ensures clean disconnect on sustained over-voltage that the stabiliser can’t handle.
Voltage protector vs SPD — what’s the difference?
SPD (Surge Protection Device) clamps fast transients (lightning, switching surges) in microseconds and stays in circuit. Voltage protector disconnects the load on sustained out-of-range voltage (seconds). Different physics, different threats — install both for full coverage.
What size voltage protector do I need for a 5-ton AC?
5-ton (60,000 BTU) AC draws ~25A start, ~12–14A run at 220V. A 40A voltage protector is sufficient. If the AC is alongside fridge + lighting + 2-ton inverter AC, jump to 63A for headroom.
Can a voltage protector be used for 3-phase commercial loads?
Yes — use a 3-phase voltage protector (CNC YCVP-3P-63 or YCVP-3P-100). These monitor all three phases plus phase sequence and phase failure. Single-phase units cannot be used on 3-phase systems even with bridging.
How long does a voltage protector last in Pakistan?
Internal relay / contactor is rated for ~100,000 operations under normal load. With 5–10 trips per day in a typical Pakistani urban grid, that’s 8–15 years before contact wear. The control electronics typically outlast the relay. CNC provides 1-year manufacturer warranty against control PCB failure.
Are CNC voltage protectors PSQCA approved?
Yes — all CNC YCVP and YCSi-VP series carry PSQCA "P" mark with serial-traceable certificates. Internal components conform to IEC 60947-4-1 (contactor) and IEC 61810-1 (relay) standards, with PA66-GF housing rated UL94 V-0 for flame retardancy.
Do you ship voltage protectors nationwide in Pakistan?
Yes — CNC ships across Pakistan via TCS, Leopards, M&P, and franchise dealers. 1–3 day delivery to Lahore / Islamabad / Faisalabad / Multan from Karachi warehouse. 4–7 days to remote districts (Skardu, Gwadar, Turbat). Free delivery for orders > PKR 25,000.
