Features Practical Use: Used to protect power distribution facilities from overload and short circuit damage. It can also be used for control and isolation. Quick Decoupling: Electromagnetic decoupling system can quickly decouple when the circuit is short circuited to protect the safety of the circuit. Arc Extinction: DC arc extinguishing is more difficult than AC, and the DC circuit breaker has a magnetic system for auxiliary arc extinguishing. Extensive Using: Enables flexible application in DC power systems, ship power systems, solar photovoltaic systems, electric motorcycle and so on. Easy to Install: The modular structure can be conveniently installed with screw clamp wire and through 35mm DIN rail installation.
