Mold Case Circuit Breaker
The JCM1 Series circut breaker is a product of innovation leveraging international technology.Compatible with 50Hz or 60Hz AC systems, it boasts a rated insulation voltage of 800V (500V for JCM-63) and supports operating voltages up to 690V (JCM1-100: 400V-690V) with a rated current of 800A. Primarily designed for distribution network circuits, it safeguards against overload, short circuits, undervoltage, and serves as protection for infrequent motor starts. Its compact design, high breaking capacity, minimal arc flash, and anti-vibration features make it ideal for both land and marine applications. Compliant with GB 14048.2 and IEC 60947-2 standards and CCC certified.
