Automatic Changeover Switch Price in Pakistan 2026 — CNC Buyer's Guide
Automatic Changeover Switch — Pakistan Quick Answer (May 2026)
An automatic changeover switch in Pakistan transfers your electrical load from WAPDA / K-Electric mains to a backup generator or solar inverter within 50–200 milliseconds of detecting power failure — without any manual intervention. Current 2026 PKR prices range from Rs. 6,200 (2P 63A YCQ4) for small homes to Rs. 89,000 (4P 630A YCS1) for commercial loads. For a typical Pakistani home with a 5–15 kVA generator, a CNC YCQR 2P 63A at Rs. 6,300 or YCQ4 2P 100A at Rs. 6,200 is the most-bought model in 2026.
Three common names, same device: automatic changeover switch · auto changeover switch · automatic transfer switch (ATS). The terminology varies but the function is identical — automatic load transfer between two power sources.

Which Automatic Changeover Switch Do You Actually Need?
The right model depends on three things: your generator size (kVA), your phase configuration (single or 3-phase), and whether you're also switching solar DC.
| Your Setup | Recommended Model | Why | Price (PKR) |
|---|---|---|---|
| 1.5 ton AC + lights — 3 kVA gen | YCQ4 2P 63A | Cheapest reliable option, 63A handles up to ~14 kW continuous | 6,200 |
| Full home — 7–10 kVA gen | YCQR 2P 63A | Tested for repeated cycling, 30% off in 2026 | 6,300 |
| Shop / large home — 12–15 kVA | YCQ4 2P 100A | Headroom above 63A nameplate, future-proof | 6,200 |
| 3-phase home (rare) | YCQR 4P 63A | True 4-pole including neutral switching | 7,200 |
| Office / 30–50 kVA gen | YCQ4 4P 100A | 3-phase industrial-grade, IEC 60947-6-1 | 7,200 |
| Solar hybrid inverter (DC) | YCQ4 DC 2P 500V 100A | Rated for solar DC switching — AC ATS will fail | 7,300 |
| Factory / 100+ kVA gen | YCS1 4P 200–630A | Heavy-duty industrial frame | 18,500–89,000 |
Automatic Changeover Switch vs Manual Changeover — Which Should You Buy?
This is the most-asked question on our WhatsApp helpline. Short answer: get automatic if you own a generator that auto-starts, otherwise the price gap is hard to justify for a generator you start manually anyway.
| Factor | Manual Changeover | Automatic Changeover (ATS) |
|---|---|---|
| Transfer time | 10–60 seconds (you flip the lever) | 50–200 milliseconds |
| Generator must start automatically | No | Yes (AMF generator) |
| Risk of frying inverter / TV during transfer | None (you control timing) | None (fast enough to not register) |
| Price 2P 63A (PKR) | 1,800–3,500 | 6,200–6,700 |
| Best for | Old/manual-start generators, low-budget | Auto-start generator, frequent outages, business |
| UPS / inverter battery still needed? | Yes (for the 10–60 sec gap) | Optional (200 ms gap is below UPS threshold) |
Bottom line: If you bought a generator with AMF/auto-start capability, the ATS pays itself back in the first 6 months by removing the need for a dedicated battery UPS. If your generator only starts manually, buy a manual changeover switch instead and save Rs. 4,000–5,000.
Single-Phase or 3-Phase? Pole Count Explained
The "2P / 3P / 4P" marking on every automatic changeover switch tells you how many wires it physically interrupts.
- 2P (2-pole) — switches one Live and one Neutral. Required for any single-phase 230V supply in Pakistan. ✅ Most Pakistani homes need this.
- 3P (3-pole) — switches 3 Live wires, no Neutral. Used in 3-phase TT/IT systems. Uncommon in Pakistan residential.
- 4P (4-pole) — switches 3 Lives + Neutral. Required for 3-phase TN-S systems (Pakistani industrial standard). ✅ Factories, shops with 3-phase meter.
If your electricity bill shows "1-phase" connection — you need 2P. If it shows "3-phase" — you need 4P (do NOT use 3P in Pakistan, the neutral must switch with the live wires for safety).
Sizing the Amp Rating — Don't Buy Too Small
Add up the peak load (in amps) of every appliance that will run during a power cut, then choose the next ATS rating above. For a typical Pakistani 5-marla home:
| Appliance | Typical amps (230V) |
|---|---|
| 1.5 ton inverter AC | 7–10 A |
| 2 lights, 2 fans, TV, fridge | 6–8 A |
| Water motor (0.5 HP) | 4 A |
| Kitchen exhaust + microwave (occasional) | 6 A |
| Total continuous | ~30 A |
| Safety margin (1.5× rule) | 45 A |
| → Choose | 63A ATS |
For households with 2 ACs or any electric water heater, jump to 100A. Don't try to save Rs. 1,000 by buying 40A for a 30A continuous load — the contacts will pit and the ATS will fail in 2–3 years.
Solar / Hybrid Inverter ATS — Special Notes
Standard ATS units are AC-only. If you're switching the DC side of a solar inverter (e.g., between battery bank and grid-tied DC bus), you need a PV-rated DC ATS. CNC offers the YCQ4 DC 2P 500V 100A at Rs. 7,300 — properly rated for solar DC switching with arc-quenching specifically designed for DC current.
Common mistake: installers in 2024–2025 routinely used AC ATS on solar DC circuits. These units typically fail within 6 months because AC arcs self-extinguish at the AC zero-crossing, while DC arcs do not. Always use a DC-rated ATS for any solar DC switching.
CNC vs Schneider vs Chint vs Tomzn — 2026 Price Comparison
| Brand | Model | Spec | PKR Price | Origin | Warranty |
|---|---|---|---|---|---|
| CNC Electric | YCQR | 2P 63A | 6,300 | China (PSQCA-approved) | 1 year |
| Schneider | ATSE 63 | 2P 63A | 32,000–38,000 | France/Indonesia | 2 years |
| Chint | NH40Z | 2P 63A | 14,500–17,000 | China | 1 year |
| Tomzn | TOQ4 | 2P 63A | 9,800–11,500 | China | 6 months |
| Generic (no-brand) | — | 2P 63A | 3,500–5,000 | China | none |
Why CNC at Rs. 6,300 beats both the Rs. 38,000 Schneider AND the Rs. 5,000 generic: Schneider is over-spec'd for a Pakistani home (you're paying for 50-cycle endurance you'll never use), and generic no-brand units skip the safety certifications. CNC sits at the sweet spot — PSQCA-approved, IEC 60947-6-1 compliant, 1-year warranty, with the exact spec a Pakistani installation needs.
Where to Buy in Pakistan — Avoid 3 Common Scams
- Fake "CNC" branding on used units — Hall Road Lahore has refurbished units relabeled as CNC. Always check the holographic PSQCA sticker.
- 50A sold as 63A — Some sellers swap labels. Open the cover before payment; the internal stamping should match.
- "DC-compatible" AC ATS — Several sellers on Daraz claim a Rs. 5,000 AC ATS works for solar. It does not. Only PV-marked models with DC rating are safe.

Frequently Asked Questions — Automatic Changeover Switch Pakistan
Q1: What is the cheapest automatic changeover switch in Pakistan?
The cheapest genuine, PSQCA-approved automatic changeover switch in Pakistan is the CNC YCQ4 2P 63A at PKR 6,200 (May 2026). Avoid no-brand units priced below Rs. 5,000 — they typically lack certification and fail within 6–12 months.
Q2: Is an automatic changeover switch the same as ATS?
Yes. "Automatic changeover switch", "auto changeover switch", and "automatic transfer switch (ATS)" all refer to the same device. ATS is the international/technical term; "automatic changeover" is the colloquial Pakistani term. Functionally identical.
Q3: Do I need an automatic changeover if I have an inverter battery system?
Yes if your inverter does NOT have built-in transfer switching (most older Inverex/Homage units don't). The ATS goes between the mains, generator, and your inverter input. Modern hybrid solar inverters (Solis, Goodwe, Growatt 2024+) have built-in ATS — no separate unit needed.
Q4: Can I install an automatic changeover switch myself?
If you understand basic electrical wiring (live, neutral, earth, breaker terminals) — yes. The wiring diagram is on the front cover. However: connecting the generator-start signal wire requires understanding your generator's AMF panel pin-out. For 3-phase or generator AMF wiring, always hire a licensed electrician.
Q5: How fast does an automatic transfer switch operate?
CNC YCQR and YCQ4 series transfer in 50–200 milliseconds after mains failure. The generator itself takes 8–15 seconds to start, so total dead time = generator start time, not ATS time. Once generator is online, transfer back to mains is essentially instantaneous.
Q6: What is the difference between 2P and 4P automatic changeover?
2P switches 1 Live + 1 Neutral (single-phase, 230V — Pakistani homes). 4P switches 3 Lives + 1 Neutral (3-phase 400V — factories, large shops, commercial). Use whichever matches your electricity meter's connection type.
Q7: How long does a CNC automatic changeover switch last?
CNC YCQ series are rated for 10,000 mechanical operations and 2,500 electrical operations at full load. For a typical Pakistani home with 4–6 power cuts per day, that's 5–7 years of normal life. Heavy-load commercial installations (50+ daily cycles) should plan for replacement at year 3.
Q8: Is the CNC ATS PSQCA certified?
Yes. All CNC YCQ-series automatic changeover switches sold by CNC Electric Pakistan carry both PSQCA approval and IEC 60947-6-1 compliance. The holographic certificate sticker is visible on the side of each unit — verify before payment.
Q9: Can an automatic changeover switch be used with solar inverters?
Yes, but only PV-rated DC models. Use the CNC YCQ4 DC 2P 500V 100A (PKR 7,300) for solar DC switching. Standard AC ATS will fail when used on DC circuits because they cannot extinguish DC arcs.
Q10: What warranty does CNC Electric Pakistan offer on ATS units?
1-year manufacturer warranty covering electrical and mechanical defects. Warranty claims are processed within 7 working days at the CNC service centre on College Road, Township, Lahore.
