Product introduction

YCW3 Series Universal Circuit Breaker has rated current from 200A to 6300A and rated working voltage of 400V/415V and 660/690 V, suitable for 50/60 Hz AC. It is mainly used in distribution network to distribute electric energy, protect lines and power supply equipment from overload, undervoltage, short circuit, single-phase grounding and other faults.
The circuit breaker can be widely used in power stations, factories, mines and modern high-rise buildings, especially in the distribution system of intelligent buildings.
Meet the standards: GB/T14048.2, IEC60947-2.
