The WCM8E-125M Molded Case Circuit Breaker (MCCB) is a state-of-the-art solution designed for reliable electrical protection in commercial, industrial, and marine applications.
With a rated insulation voltage of 800V and a compact design, the WCM8E-125M provides comprehensive circuit protection against overload, short circuit, and under-voltage scenarios.
WCM8 series moulded case circuit breakers are available in four different breaking capacity classes: C-type (low), L-type (standard), M-type (high) and H-type (extra high), ensuring customised solutions based on different short-circuit breaking capacity (Icu) requirements.
It is designed to protect distribution lines and connected electrical equipment from damage, thereby improving system reliability and safety.
Adopting internationally advanced design and manufacturing technology, this moulded case circuit breaker performs well in environments where infrequent line switching or motor starting is required at AC 50Hz, with a rated working voltage of up to 690V, making it ideal for switchboards, motor control centres, industrial machinery and marine power systems.
Its rugged structure and customizable configuration make it ideal for OEM/ODM electrical solutions that require high reliability and space efficiency.
