4 Pole 63A YCQ1B Automatic Transfer Switch | Reliable Power Backup

ATS 4 pole 63A is the right choice when a three-phase board needs automatic source transfer instead of a manual changeover. This YCQ1B unit is listed at Rs.7,800 on CNC Electric Pakistan. It suits generator backup panels, small commercial buildings, workshops, lifts, pump rooms, and other sites where WAPDA failure should shift load to backup power without waiting for an operator.

Key Features

• 4 pole automatic transfer switch for three-phase systems
• 63A rating for compact backup panels
• Automatic and manual operating modes
• Fast transfer with quoted conversion time up to 2 seconds
• Built for main and standby source switching
• IEC 60947-6-1 family context for ATS equipment

Technical Specifications

Product Range

Applications

This ATS is built for sites that cannot wait for someone to walk to the panel and change sources by hand. It fits workshop backup boards, generator panels, small commercial buildings, and utility rooms where the load should move to standby power automatically. In Karachi, this kind of 4 pole ATS is common in pump and building-service panels where downtime causes immediate operational problems.

How to Choose the Right ATS

ATS vs Alternatives

Installation Guide

1. Mount the ATS in a rigid three-phase enclosure with correct source and load labeling.
2. Verify main source, standby source, and load terminals before energizing.
3. Set the control supply correctly for the 220V operating circuit.
4. Test both automatic and manual transfer before handover.

What This Product Does NOT Protect Against

This ATS does not replace upstream short-circuit protection, surge protection, or voltage control. It transfers sources. It does not clean poor voltage, stop lightning surges, or act like an MCCB.

For a complete panel, pair it with surge protection devices, a proper voltage protector, and the right MCCB breakers.
