AC 4P Changeover Breaker Din Rail 63A, 100A, 125A - YCBZ

This 4 pole changeover breaker gives manual source transfer inside the panel without moving to a large external rotary switch or an automatic ATS. Available in 63A, 100A, and 125A, it fits mains-to-generator, mains-to-inverter, and source-selection boards where the operator wants a clean DIN rail layout. Price starts at Rs.2,450 from CNC Electric Pakistan.

Key Features

• 4 pole manual source transfer for phase + neutral switching
• DIN rail mounting for compact internal panel layouts
• 1-0-2 switching positions for clear source selection
• Available in 63A, 100A, and 125A local variants
• IEC 60947-3 switch disconnector class
• Useful for generator panels, inverter transfer boards, and utility backup systems

Applications in Pakistan

This 4 pole version is the right pick when neutral switching matters. That is common in generator panels, inverter transfer boards, and three-phase backup systems where the installer wants phase plus neutral isolation during source change. It fits workshop panels, commercial utility rooms, and small factory backup boards better than a 3-pole unit when the panel design calls for a switched neutral.

How to Choose the Right Variant

Comparison

What This Product Does NOT Protect Against

This switch selects the source. It does not stop overvoltage, undervoltage, surge damage, short circuit, or low generator frequency. It is not an automatic transfer switch. It also does not replace the upstream breaker or MCCB protecting the panel.

For a complete backup board, pair it with the right Circuit Breakers, Voltage Protectors, Surge Protection Devices, and where automatic transfer is required, the correct Automatic Transfer Switches.

Installation Guide

1. Mount the switch on a 35mm DIN rail inside a rigid enclosure.
2. Identify source I, source II, and load terminals before wiring.
3. Use the correct conductor size for the selected amp rating.
4. Check the center OFF position and source isolation before energizing.
