YIFA Low voltage electric prepaid molded case circuit breaker MCCB YFM1 series

Product Description

The circuit breaker is classified as type L (standard type), Type M( higher make-break trpe) and Type H(high make-break type) by the rated limit short-circuit make-break capacity and short flashover.

Its rated insulation voltage is 800V. It is suitable in the AC 50Hz or 60Hz power distribution networks andcircuits with a rated operating voltage up to 690V and a rated current up to 800A and is used for distributing electric energy and protecting circuits and power equipment from overload, short circuit and undervoltage. Ia can be also used as protection against non-frequent startup, over load,short circuit and under voltage.

This series circuit breaker is provided with metal vapor jet control technology that improves breaking capability greatly. And run-on plates are mounted on the arc extinguishing chamber and static contact respectively that can improve ability to extinguish arc and make short flashover distance. And a dual-locking machanism is mounted on driving mechanism that takes reliable work and proofs vibration, the driving shaft is of good stiffness, no distortion and a moving contact base is mounted on it, three-phase contact has perfect synchronism. The simple structure is superior among high-breaking circuit breakers.
