Swm1E 250M 3P Current Electrical Air Safety MCCB Molded Case Circuit Breaker Manufacturer factory

Product Overview

Description

APPLICATION
SWM1E series electronic molded case circuit breaker is one of the new circuit breakers developed and developed by our company using international advanced design and manufacturing technology. Its rated insulation voltage is 800V, suitable for AC 50Hz, rated working voltage 400V, rated working current up to 800A for infrequent conversion and infrequent starting of the motor. The circuit breaker has overload long-delay inverse time, short-circuit short-delay inverse-time, short-circuit short-delay definite time, short-circuit instantaneous and under-voltage protection functions, which can protect lines and power equipment from damage.
