Features Main Use: 4P miniature circuit breakers are used to protect low-voltage electrical systems from overcurrent damage caused by overload or short circuit. Durable Material: The circuit breaker shell is made of nylon PA66 material, which has good safety and flame retardant performance and long service life. Mainly used for the lighting of office buildings and residential buildings. DIN Rail Mounting: Modular construction design with bistable locking clips for easy mounting on DIN standard rails in distribution boxes. Quick trip to ensure the reliable operation of the load and prolong the service life of the electrical circuit breaker. It can also act as a switch for DC load circuits. Voltage Capacity: The rated voltage and current are AC 400V 63A, the rated ultimate short-circuit breaking capacity is 4500A, and the operation is safe and reliable. Wide Range of Applications: The circuit protection switch has a compact structure and is widely used in various DC systems such as lighting systems in office buildings and residential buildings, solar panel grid-connected systems, and wind-solar hybrid systems.
