YCM3 Moulded Case Circuit Breaker
Application
YCM3 series moulded case circuit breaker is one of the most advanced typebreaker in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection in circuit of AC 690V 50/60Hz,rated current from 12.5A to 630A. Its rated insulation voltage is 690V. It can make and break the unfrequently circuitunder normal conditions. It takes protecting effect when mouse cage motors unfrequently start, making&breaking and protecting against overload, short circuit and lacking voltage.
