Feature:1. Rapid Response: Highly sensitive operating mechanism has the lowest moment of inertia, and the time from short circuit fault to tripping action of the mechanism is very short.2. Dual Protections: The tripping mechanism is composed of double silver plate overload inverse time tripping mechanism and short circuit instantaneous electromagnetic mechanism, features overload and short circuit dual protection.3. Effective Arc Extinguishing: The contact arc extinguishing system adopts special pilot arc angle and passage chamber, and has remarkable current limiting characteristics.4. PC Shell: The shell is made of special PC plastic with high flame retardant and high strength, with strong impact resistance and light weight.5. Wide Usage: Modular structure, standard 36mm DIN rail installation, the circuit breaker is easy to install, can be widely used for DC power supply system, ship power system, solar photovoltaic system or other DC systems.Specification:Item Type: DC Circuit BreakerMaterial: PC, SilverRated Ultimate Short Circuit Breaking Capacity (Household Icn): 10KAMechanical Life: 20000 timesApplicable Temperature: -35 to +70Installation: Standard 36mm Guide Rail Installation.Package List:1 xDC Circuit Breaker
