General
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.
