It is used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation. Quick trip, the electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the circuit safety. Arc extinguishing, DC arc extinguishing is more difficult than AC. The DC miniature circuit breaker has a magnetic system for auxiliary arc extinguishing. Applications for DC power systems, marine power systems, solar photovoltaic systems or other DC systems. Installation, screw clamp wire, 35mm DIN rail installation.
