Features Fast decoupling The electromagnetic decoupling system can immediately decouple when the circuit is short-circuited, ensuring your operational safety. DC Circuit Breakers Our circuit breakers can be used to secure power distribution equipment from overload and short circuit damage, as well as control and insulation. Wide Application The circuit breaker can be used in DC systems, marine power systems, solar photovoltaic systems or other DC systems. Rail Mounting: This circuit breaker is modular and clamped to the wire and mounted with 35mm DIN rails. Arc extinguishing This DC circuit breaker has a magnet system for auxiliary arc extinguishing, which is more difficult at DC than AC. Specification: Item Type:4P DC Circuit Breaker Model: DZ47s 63Z.
