Manufacture Electric Type Fixed MCCB Circuit Breaker 3p 630A Molded Case Circuit Breaker
WCM1 series MCB is one of updated type MCCBs researched and developed by the company by using advanced design and manufacture technology internationally.
The WCM1 series MCCB is a new type developed using advanced technology. It has 800V (WCM1-63 500V) rated insulation voltage, suitable for 50Hz AC, ≤690V (WCM1-63 ≤400V) operation, and infrequent motor starting. With overload, short-circuit, and undervoltage protection, it classifies as C, L, M, or H type based on Icu. Compact, high breaking capacity, short flashover, and vibration-resistant, it is ideal for land and ship use, supporting vertical and horizontal mounting.
Our factory has over 20 years of expertise in circuit breaker production, with annual domestic and international sales exceeding 500 million RMB. Leveraging automated production lines, we ensure stable product quality. Our high-performance circuit breakers are backed by comprehensive certifications, delivered by our dedicated R&D and sales teams committed to meeting your requirements.
