4 Pole 100A YCQ4 Automatic Transfer Switch | Reliable Power Changeover Switch

ATS 4 pole 100A is built for panels that must shift from mains to backup supply without waiting for a person to flip a handle. This model is listed at Rs.7,500 on CNC Electric Pakistan. It suits generator changeover panels, small commercial backup boards, clinics, offices, and three-phase loads where manual changeover is too slow.

Key Features

• 4 pole automatic transfer switch, 100A, AC400V class.
• Automatic and manual operation both available.
• Fast transfer, published at under 50ms on the YCQ4 family and under 2 seconds on the local page.
• DIN rail / household rail installation style for compact boards.
• IEC 60947-6-1 ATS class on the local page.
• Good fit for mains-generator and mains-backup source transfer.

Applications

This ATS fits three-phase panels where supply must move automatically to backup. Common use includes clinics, offices, utility rooms, generator boards, lift panels, and small production units. In Karachi generator rooms and Lahore commercial backup panels, this size is useful when 63A feels small but a larger ATS frame adds unnecessary cost and space.

What This Product Does NOT Protect Against

This ATS does not replace upstream short-circuit protection, surge protection, or voltage protection. It transfers source. It does not correct bad voltage, absorb lightning surges, or replace a full protection scheme.

Complete the panel with circuit breakers, voltage protectors, surge protection devices, and if you need manual transfer only, see changeover breakers.

Installation

1. Mount on the proper rail / enclosure with phase identification complete.
2. Use correct source and load wiring. Verify control voltage before energizing.
3. Test auto and manual modes before handing over the panel.
