ATS Automatic Transfer Switch Price in Pakistan 2026 — Buyer's Guide

Automatic Transfer Switch (ATS) prices in Pakistan in 2026 range from Rs. 6,700 for a single-phase 63A residential 2-pole ATS to Rs. 245,000+ for a 4-pole 400A industrial ATS with full PLC controller and grid + generator + solar three-source switching. The right ATS for you depends on three things: total load (amps), number of sources you need to switch between (grid + generator only, or grid + UPS + solar), and whether you need motorised or contactor-based switching. This guide lists current 2026 PKR prices for every common ATS configuration in Pakistan, walks through generator and solar-hybrid sizing, compares ATS vs manual changeover, and shows where each fits. For the broader breaker-family pricing, see our complete circuit breaker price list 2026; for manual changeover instead, the changeover breaker complete guide.

What Is an Automatic Transfer Switch (ATS)?

An Automatic Transfer Switch (ATS) is a power-switching device that automatically transfers your electrical load from one supply source to another when the primary source fails — most commonly grid → generator, but increasingly grid → solar → generator in modern Pakistani installations. Unlike a manual changeover switch (which requires someone to flip a handle), an ATS senses voltage loss within milliseconds and switches over automatically, then transfers back when the primary source returns. Critical for homes, hospitals, banks, data centres, telecom sites, and any business where unattended switching is required. Governed by IEC 60947-6-1 standard.

ATS Sizing for Generators in Pakistan

Generator ATS sizing is straightforward but routinely done wrong. The rule:

ATS rated current = Generator full-load current × 1.25 (safety factor)

For typical generator sizes used in Pakistan:

• 5 kVA single-phase generator (~22 A FLA): use 2P / 40A ATS — Rs. 6,700
• 10 kVA single-phase (~44 A FLA): use 2P / 63A ATS — Rs. 9,800
• 15 kVA single-phase or 3-phase (~22 A 3φ): use 4P / 40A ATS — Rs. 18,500–22,500
• 30 kVA 3-phase (~43 A 3φ): use 4P / 63A ATS — Rs. 22,500
• 62.5 kVA 3-phase (~90 A 3φ): use 4P / 125A ATS — Rs. 42,000
• 125 kVA 3-phase (~180 A 3φ): use 4P / 250A ATS — Rs. 78,000
• 250 kVA 3-phase (~360 A 3φ): use 4P / 500A ATS with PLC — Rs. 165,000
• 500 kVA 3-phase (~720 A 3φ): use 4P / 1000A ATS with PLC — Rs. 320,000+ (project quote)

ATS for Solar Hybrid Systems (3-Source Switching)

Pakistan's solar adoption now drives the fastest-growing ATS use case: 3-source switching between grid, generator, and solar inverter output. The PLC-driven controller decides priority dynamically:

1. Solar (preferred when available) — uses free PV energy first; surplus exports to grid under net metering
2. Grid (default backup) — when solar drops below load, grid takes over seamlessly
3. Generator (last resort) — only starts when both solar and grid are unavailable; prevents diesel burn during load shedding if solar can carry load

For a 5–10 kW residential hybrid, the 3-source ATS plus matching DC breakers, SPDs, and a complete solar bundle typically lands at Rs. 180,000–280,000 fully installed. For a 50–100 kW commercial hybrid, the 3-source ATS alone is Rs. 195,000–320,000. NEPRA's 2026 net-metering rules affect inverter and ATS configuration — see the NEPRA net-metering 2026 guide and the solar export limit explainer.

ATS vs Manual Changeover — Decision Matrix

A manual changeover is a fraction of the cost of an ATS but requires someone present to operate it. Use this matrix to decide:

Switching Mechanism — Contactor vs Motorised MCCB

Contactor-Based ATS

Two contactors with mechanical and electrical interlock — when one closes, the other physically cannot. Lower cost (Rs. 6,700–28,000 typical range), faster switching (~50 ms), good for currents up to about 125 A. Best for residential and small commercial. The contactor coil draws holding current continuously while energised — adds 5–15 W to electricity bill.

Motorised MCCB-Based ATS

Two MCCBs with motor-operating mechanisms and electrical interlock. Higher cost (starts at Rs. 42,000 for 100A), slower switching (~200 ms), but no continuous holding current and much higher current capability (up to 1,600 A). Standard for commercial and industrial. Includes built-in over-current and short-circuit protection — eliminates the need for separate upstream MCCBs.

PLC Controller — When You Need One

For 2-source switching (grid + generator only), a basic ATS controller (voltage sensor + delay timer + transfer logic) is built-in and sufficient. For more complex requirements, a programmable PLC controller is required:

• 3-source switching (grid + generator + solar) — PLC mandatory
• Custom transfer logic — e.g., "transfer to generator only if outage > 5 minutes" to avoid unnecessary genset starts during brief WAPDA dips
• Load shedding management — drop non-essential loads on generator to fit gen capacity
• Remote monitoring — Modbus / SCADA / WiFi reporting of source status and transfer events
• Soft-load transfer — open-transition with synchronised retransfer (no flicker on retransfer to grid)
• Generator exercise schedule — auto-runs the genset weekly under load to prevent fuel-system clogging

PLC option adds Rs. 25,000–65,000 to base ATS cost depending on I/O count and comms.

ATS Installation Tips from Pakistani Electricians

• Configure the right transfer delay. Default 3-second delay before generator transfer prevents nuisance switches during 1–2 second WAPDA flickers. For hospitals, set to 1 second; for general residential 5–10 seconds is fine.
• Set generator warm-up time correctly. Most diesel gensets need 10–30 seconds of unloaded warm-up before accepting load. The ATS should wait this period after starting the genset before closing its load contactor.
• Don't skip the upstream MCCB. Even with a motorised-MCCB ATS, install separate MCCBs on grid and generator inputs for isolation during maintenance. Pair with appropriate RCCBs for earth-leakage protection.
• Install SPDs on both sources. Grid SPD upstream protects against utility lightning surges; generator-side SPD protects against generator voltage transients. See our SPD collection.
• Test monthly. Manually trigger a transfer and re-transfer once a month. Mechanism stiffness and contactor wear are detected before they cause real-world failure.
• For solar-hybrid installations, coordinate the ATS with the inverter's auto-island detection. Misconfiguration can cause anti-islanding shutdown during grid outage. Also see the solar DB box guide.

How to Spot Counterfeit ATS Units in Pakistan

1. PSQCA mark on the enclosure. Genuine units carry it; counterfeits skip it.
2. Mechanical interlock test. Try to manually close both contactors simultaneously. If they can both engage at once, the interlock is fake and the unit can short grid to generator.
3. Controller branding. Genuine CNC ATS controllers have the CNC logo laser-etched on the controller faceplate, not a sticker.
4. Weight test. A genuine 100A 4-pole motorised ATS weighs ~14 kg. Counterfeits with lightweight contactors weigh 8–10 kg.
5. Buy from authorised channels. CNC's official store at cncelectric.pk, the Daraz CNC store, or our listed dealers (about-us). Use the AI chatbot to confirm a model number is genuine before purchasing.

Frequently Asked Questions

What is the price of an ATS for a 5 kVA generator in Pakistan?

For a 5 kVA single-phase generator (~22 A FLA), use a 2-pole 40A contactor-based ATS — Rs. 6,700 from CNC YCQ1B series. Includes voltage sensing, configurable transfer delay, and 5-year warranty.

What is the price of an ATS for a 100 kVA generator?

For a 100 kVA 3-phase generator (~145 A FLA), use a 4-pole 200A motorised MCCB ATS — Rs. 65,000–78,000 from CNC YCQ7 series. Add Rs. 25,000 for PLC controller if you need custom transfer logic.

Can an ATS handle solar + grid + generator simultaneously?

Yes — but you need a 3-source PLC-controlled ATS, not a basic 2-source unit. Prices from Rs. 85,000 (100A) to Rs. 320,000 (400A). The PLC handles solar-priority logic and grid-tie islanding interlocks.

How fast does an ATS switch over?

Contactor-based ATS: ~50 ms switching time once the transfer command is given. Motorised MCCB ATS: ~200 ms. Total time from grid loss to generator carrying load is typically 8–15 seconds (controlled by the genset start delay, not the ATS itself).

Do I need an ATS or just a manual changeover?

If someone is always present to flip the switch (e.g., your home with auto-start generator and you don't travel), a manual changeover at Rs. 3,500–8,500 is enough. If the site is unattended (telecom, remote pump, your home when you're away), or if you have a hospital/bank/data-centre uptime requirement, an ATS is mandatory.

Are CNC ATS units PSQCA approved?

Yes. Every CNC YCQ series ATS sold in Pakistan carries PSQCA certification, conforms to IEC 60947-6-1, and includes a 5-year replacement warranty against manufacturing defect.

Can the ATS auto-start my generator?

Yes — most CNC ATS controllers include 2-wire and 3-wire generator-start outputs. Confirm your generator has an auto-start panel (most modern diesel gensets do). The ATS triggers the start signal, waits for generator stabilisation, then closes the genset contactor.

Do you ship ATS units nationwide in Pakistan?

Yes — same-day dispatch from Lahore for in-stock units, nationwide courier to all major cities. Cash on delivery up to Rs. 100,000; bank transfer or EasyPaisa for larger orders. PLC-customised configurations have 3–7 day build time.
