Plastic shell circuit breaker (hereinafter referred to as circuit breaker) is one of the new types of circuit breakers developed by our company using international advanced design and manufacturing  technology. 

According to its rated limit short-circuit breaking capacity (LCU), it is divided into four categories: C type (basic type), L type (standard type), M type (higher breaking type), and H type (high  breaking type). 

This product has the characteristics of small volume, high breaking height, short flying arc, and anti vibration, making it an ideal product for land and ship use. Its rated insulation voltage is 800V (JM1-63 is 500V), suitable for infrequent switching and infrequent motor starting in circuits with AC 50Hz, 690V and below. The circuit breaker has overload, short circuit, and undervoltage  protection devices, which can protect the circuit and power equipment from damage. This product can be installed vertically or horizontally. This product meets the standards of IEC60947-2 and GB14048.2
