Protection System: This breaker protects power distribution systems from overload and short-circuit faults, and can also be used for control and isolation. Guaranteed Safety: The electromagnetic tripping system can trip immediately when the circuit is short-circuited, effectively protecting circuit safety. Fast Arc Quenching: DC arc quenching is more difficult than AC; this DC breaker features an extra arc-quenching magnetic system for faster response. Suitable Systems: Used for DC power systems, ship power systems, solar photovoltaic systems, or other DC systems, with excellent performance. Installation Method: The breaker features a modular structure, using screw clamps and 35mm DIN rail installation.
