YCBZ-63 Manual Change Over

YCBZ-63 Manual Change Over

The YCBZ-63 Manual Change-Over Switch is a low-voltage mechanical switch designed for manual transfer between two power sources in AC electrical systems. Rated for 63 A continuous current, it provides safe change-over between utility and alternate sources (such as generator or inverter output) under no-load or infrequent switching conditions. The switch complies with IEC/EN 60947-3 standards and is suitable for residential, commercial, and light industrial distribution panels where simple source transfer and isolation functions are required.
