ATS Changeover Switch Price in Pakistan 2026 — Automatic Transfer Buyer Guide
"ATS changeover switch" is the most-searched Pakistani term combining both the automatic-transfer-switch (ATS) function and the manual changeover semantics. Buyers Google it when they want hands-off switching between WAPDA grid, generator, and solar inverter — without manually flipping a lever every time the power dips. The right ATS sized correctly for your home or business pays back its premium within 12 months via reduced generator runtime and zero brownout damage.
This guide covers ATS changeover switch prices in Pakistan for 2026, manual vs automatic transfer, 2-pole vs 4-pole sizing, and the matching CNC components for residential, commercial, and industrial Pakistani installations.
1. What is an ATS changeover switch?
An ATS (Automatic Transfer Switch) is a changeover switch with a control circuit that detects loss of the primary source (WAPDA grid) and automatically transfers the load to a backup source (generator, solar inverter, or battery-backup). Unlike a manual changeover that requires you to physically flip a lever, an ATS does the switching in 1-3 seconds without human intervention.
Three main types:
- Manual changeover — lever or rotary, you flip it; cheapest at PKR 2,800-6,800
- Semi-automatic changeover — motorised rotary; you press a button, motor turns the rotary
- Fully automatic ATS — detects grid loss, switches automatically; PKR 35,000-180,000 depending on size

3. Sizing ATS changeover for your install
- Calculate peak load: sum your largest concurrent draws (e.g., 2 ACs + fridge + lights + geyser = ~6 kW).
- Convert to amps: 6 kW / 220V = 27A single-phase, or 6 kW / (380V×1.732) = 9A 3-phase per leg.
- Add 25% safety margin: 27 × 1.25 = 34A.
- Pick next standard rating: 63A, 100A, 200A, 250A, 400A, 630A.
- Pole count: 2P for single-phase, 4P for 3-phase (always include neutral switching).
Quick lookup for typical Pakistani installations

4. ATS changeover switch wiring
- Source 1 (WAPDA grid) → through main isolator → into ATS source-1 terminals (top).
- Source 2 (generator OR solar inverter) → through its dedicated isolator → into ATS source-2 terminals.
- Load (your DB box) → connected to ATS load terminals (bottom).
- Control wiring: ATS gets 24V DC or 230V AC from the grid for its sensing circuit. When voltage drops below threshold (typically 195V), the ATS switches to source 2 within 1-3 seconds.
- Restoration: when grid returns and stabilises for 5-10 seconds (programmable), ATS switches back to source 1.
5. Manual changeover vs automatic ATS — which to choose
| Manual changeover | Automatic ATS | |
|---|---|---|
| Switching time | 5-30 seconds (human reaction) | 1-3 seconds (automatic) |
| Price for 100A | PKR 5,800-6,800 | PKR 35,000-48,500 |
| Reliability | Very high — no electronics | High — electronics-dependent |
| Best for | Daytime users at home, manual generator start | Hands-off, nobody-home, frequent outages |
| Pakistani market dominant choice | Small homes | 3-bed+ homes, businesses, factories |
6. CNC vs Schneider vs Hyundai — honest comparison
| CNC YCQ4 / YCS1 | Schneider Compact NSX | Hyundai HiATS | |
|---|---|---|---|
| 100A 4-pole price (PKR) | 48,500 | 165,000 | 125,000 |
| 250A 4-pole (PKR) | 72,500 | 295,000 | 225,000 |
| Switching time | 1.5-3 sec | 1-2 sec | 1.5-2.5 sec |
| IEC 60947-6-1 | Yes | Yes | Yes |
| Solar PV variant | Yes (YCQ4-PV) | Limited | No |
| Warranty Pakistan | 5 years | 2 years | 2 years |
For typical Pakistani residential and light-commercial use, CNC delivers Schneider-class functionality at 30% of the price. Schneider's premium is justified only for mission-critical commercial (medical, data centre) where 1-second switching matters.
7. FAQ
Cheapest ATS changeover switch in Pakistan 2026?
For manual rotary: CNC EP-2P at PKR 4,200 (63A 2-pole). For fully automatic: CNC YCQR-63A at PKR 28,500 (63A 4-pole rotary motor-driven).
Difference between ATS and changeover switch?
Changeover = the physical switch device. ATS = changeover + automatic control circuit. All ATS are changeovers; not all changeovers are ATS.
Will an ATS work with my Pakistani solar inverter?
Yes — CNC YCQ4 + YCS1 ATS units work with all standard solar hybrid inverters (Inverex, Knox, Crown, Solis). For pure PV / battery + grid + generator combinations: use the YCQ4-PV variant.
What size for a typical 3-bed Pakistani home with 2 ACs?
2 ACs + fridge + lights + general loads = ~25-35A continuous draw. YCQ4-2P-100A at PKR 35,000 fits comfortably with margin for future expansion.
How does the ATS know when to switch back to grid?
The control circuit monitors source-1 voltage. When grid returns and stabilises for a programmable delay (typically 5-15 seconds), the ATS switches back. This prevents nuisance switching during grid flickers.
