MM1 series molded case circuit breaker (hereinafter referred to as breaker) is the company adopts international advanced design and manufacturing technology research and development of new circuit breakers. Rated insulation voltage is 800V, suitable for AC 50Hz (60Hz), rated working voltage 690V and below (DC 250V and below), rated current up to 1250A circuit for frequency conversion and not infrequent start motor for use. Circuit breaker with overload, short circuit and under voltage protection devices, power lines and equipment to protect against damage.
Circuit breakers rated according to its ultimate breaking capacity (ICU) level, divided into C-type (basic type), L-type (standard), M-type (high breaking type), H type (high breaking type) four.
The circuit breaker has small size, high breaking, short arc (part of the standard zero-arcing), anti-vibration characteristics, is ideal for use on land and marine products.
The circuit breaker can be installed vertically (ie, vertical loading) can also be horizontal (ie cross-loaded).
