Feature:1. [ARC EXTINGUISH] DC arc extinguishing is more difficult than AC, and the DC circuit breaker has a magnetic system for auxiliary arc extinguishing.2. [PROTECTIVE FUNCTION] Circuit breakers are primarily used to ensure power distribution facilities away from overload and short circuit damage, as well as for control and isolation.3. [FAST DISCONNECT] The electromagnetic decoupling system can decouple immediately when the circuit is short circuited to ensure the safety of the circuit.4. [EASY INSTALLATION] This AC DC circuit breaker is easy to install on any places, with simple modular structure and 35mm DIN rail installation way.5. [WIDE APPLICATION] Circuit breakers are widely used in solar panel grid connected systems, scenery complementary systems and other DC circuit systems.Specification:Item Type: AC DC Miniature Circuit BreakerMaterial: Pa66Rated Current: 63ARated Voltage: DC 12-400V, AC 90-400VRated Ultimate Short Circuit Breaking Capacity (Household Icn): 4000ARated Impact Withstand Voltage (Uimp): 4KVPurpose: Solar photovoltaic, electric motorcycle, electric vehicleMechanical Life: 20000 timesApplicable Temperature: -35 to +70.Package List:1 x AC DC Miniature Circuit Breaker
