The DC mini circuit breaker are produced according to IEC60898-2 and GB10963.2 standards, used in circuit breaker with voltage of 250V, 500V, 750V, 1000V and rated current of 1~100A for overload and short-circuit protection, common used at DC power, electric locomotive, metro, ship and power supply.
The circuit breaker have performance of small volome, high breaking capacity, short arcing distance, fast close and convenient installation.
Special permanent magnetic field arc blow technology can ensure the reliability and stability of DC arc breaking.
Special designed arc leading part can lead the arc to arc chamber and help the permanent magnetic lead the arc to arc fence fastly.
The circuit breaker can used with various kinds of accessories (OF, SD, MX+OF, MN etc. )
The circuit breaker can assembled to multi poles (2, 3, 4 poles) according to different voltage and breaking capacity to satisfy customer's requirement.
