Specifications

GM5B-32 Mini DC Circuit Breaker/MCB

Characteristic and application

GM5B-32 series moulded case three- levels protection DC circuit breaker complies with GB14048.2: Low voltage switchgear and control gear- Part 2. The circuit breaker could be used in storage battery of electric engineering with DC nominal voltage 110V or 220V, highest operational voltage not more than 250V and rated current from 16A to 32A. They are ideal for the over-current protection for station-line facilities and electrical equipment or occasionally switch operation. The circuit breaker is feature with small size, which short time-delay acting characteristic dependent on short-circuit current value only and unconcerned with power voltage. It is suitable for nonprofessional person.
