CM3 MCCB Molded-Case-Circuit-Breaker 63A-800A with transparent case
JINGE CM3 (M3) series transparent molded case circuit breaker is a new-generation high-performance industrial MCCB designed for global power distribution and motor protection. Compliant with IEC 60947-2 and GB 14048.2 standards, it covers rated current from 63A up to 800A and operates safely at AC 400V power systems.
With a compact structure, high breaking capacity, stable thermo-magnetic tripping and durable mechanical life, CM3 provides full protection against overload, short circuit and under-voltage faults. The transparent housing enables intuitive internal status inspection, fast troubleshooting and higher on-site safety, making it an ideal choice for modern industrial control, construction, data centers and infrastructure projects.
