4 Pole Changeover Switch 63A-125A

Looking for an automatic transfer switch price in Pakistan for a generator-backed building, commercial site, or heavier three-phase changeover setup? This CNC Electric 4 pole ATS is built for automatic source shifting between utility power and backup generation, so the load moves without manual switching during outages. For Pakistani users dealing with WAPDA interruptions, generator dependency, and more serious building loads than a basic home inverter circuit, this ATS switch is a stronger fit than a simple manual changeover. It is especially useful where clean source transfer, reduced operator dependence, and more complete pole switching matter inside a proper electrical panel.

Key Features

• 4 pole automatic transfer switch for source changeover between main utility supply and backup generator.
• Published on the live page for 63A, 100A, and 125A options, covering a wider load range than small household ATS products.
• Automatic operation mode for unattended switching during power failure and restoration events.
• Quoted transfer time of up to 3 seconds, suitable for many building, office, workshop, and commercial backup applications.
• 4 pole design gives a more complete changeover approach for sites where full line switching is part of the panel strategy.
• Built for residential, commercial, and industrial applications according to the product positioning on the live CNC Electric page.
• Practical choice for generator changeover where a manual changeover switch is too dependent on human action.
• Relevant to ATS applications guided by IEC 60947-6-1, with stronger overall panel safety when paired with Surge Protection Devices and Voltage Protectors.

Product Range / Variant Table

If your project needs a lighter-duty or compact ATS, compare the wider Automatic Transfer Switches range.

Applications

• Commercial buildings and offices where mains-to-generator transfer must happen automatically during load shedding.
• Residential blocks, villas, and larger houses using generator backup.
• Hospitals, data rooms, and managed facilities where manual switching is too slow or risky.
• Factories and workshops in Karachi, Lahore, or Faisalabad where power continuity matters for machines and operations.
• Generator-backed shopping plazas and mixed-use buildings where a 4 pole ATS switch is more appropriate than a small home backup solution.
• Panels that also need coordinated protection from SPD, voltage protectors, and upstream AC breakers.

Sizing / Selection Guide

• Choose 63A for modest building or commercial backup feeders.
• Choose 100A for stronger site loads, larger floor distribution, or medium-duty generator systems.
• Choose 125A for heavier load groups, larger buildings, or installations with future expansion.
• Choose a manual option only when budget matters more than automation. Compare with Changeover Switches and Changeover Breakers.

ATS vs Alternatives — Why CNC?

What This Product Does NOT Protect Against

• It does not replace a voltage protector. Generator sites can still face voltage issues.
• It is not a surge protection device. Use SPD where transients or lightning are a concern.
• It is not a UPS and will not provide zero-interruption ride-through.
• It does not fix poor generator quality, undersized feeders, loose terminals, or incorrect earthing.
• It should not be treated as a shortcut around proper panel design or professional changeover planning.

Installation Guide

1. Isolate both utility and generator sources fully before wiring or testing.
2. Match ATS current rating to real feeder load and generator capability.
3. Install inside a properly designed panel or enclosure. Confirm mounting dimensions before fabrication.
4. Wire mains, generator, and load exactly according to supplied markings.
5. Commission by simulating source loss, confirming automatic transfer, and verifying return behavior.
6. Complete with SPD, voltage protection, and fire-safety from the Fire Extinguisher Guide.

FAQs

What is a 4 pole automatic transfer switch?

A 4 pole ATS automatically shifts connected load between two power sources, usually mains and generator, in a complete multi-pole changeover arrangement.

Can this ATS be used for generator changeover in Pakistan?

Yes. That is the main published purpose — automatic transfer between main grid and generator power for residential, commercial, and industrial use.

What current sizes are available?

The live page lists 63A, 100A, and 125A options for this 4 pole automatic transfer switch.

How fast does this ATS switch?

Up to 3 seconds. Workable for many building and generator applications, but not zero-break UPS behavior.

What is the ATS 4 Pole price in Pakistan?

Rs. 15,000 for 63A, Rs. 17,000 for 100A, and Rs. 32,000 for 125A on the live listing.

Why is the 125A ATS price much higher?

Higher current ATS units handle heavier building loads and stronger changeover duty, which increases product size and switching capability.

Is this better than a manual changeover switch?

Yes, when the site needs automatic source transfer without relying on a person during every outage.

Can I use this for a hospital, office, or factory?

It is positioned for residential, commercial, and industrial applications when the feeder current and panel design match the selected rating.

Does this ATS protect against voltage fluctuations and surges?

No. This handles automatic source transfer. Combine with voltage protectors and SPD where those risks exist.

How should this ATS be installed?

By a qualified electrician inside a properly designed changeover panel, with mains, generator, and load wired exactly as required by the supplied markings.

For projects that need a real generator changeover solution, this CNC Electric 4 pole ATS gives you automatic source transfer, a useful 63A to 125A range, and a better fit for commercial and managed backup panels than simpler changeover devices.
