Features Rapid Response: Highly sensitive operating mechanism with the lowest moment of inertia ensures a very short time from short circuit fault to tripping action, providing rapid response to protect your circuits. Dual Protections: Features double silver plate overload inverse time tripping mechanism and short circuit instantaneous electromagnetic mechanism, offering dual protection against overload and short circuit faults for enhanced safety. Effective Arc Extinguishing: Special pilot arc angle and passage chamber result in remarkable current limiting characteristics, ensuring effective arc extinguishing to safeguard your electrical systems. PC Shell: Made of special PC plastic with high flame retardant and high strength, the shell provides strong impact resistance and light weight, ensuring durable protection for the circuit breaker. Wide Usage: Modular structure and standard 36mm DIN rail installation make it easy to install, suitable for a wide range of applications in DC power supply systems, ship power systems, solar photovoltaic systems, and other DC systems.
