Features [Short circuit protection] When the circuit is short-circuited, the electromagnetic trigger mechanism can interrupt the current stably, which is safer to use. [Easy Installation] The circuit breaker is a double locking clamp structure that can be operated horizontally during installation and can be freely disassembled and assembled in a tight environment. Wide application: Circuit breakers are often used to protect power distribution in civil, commercial and industrial buildings. Flame retardant housing: Our circuit breaker is made of nylon material Pa66, which has excellent flame retardant safety performance. [Fast arc extinguishing] The circuit breaker can quickly extinguish the arc to avoid electric fires and ensure your safety. Specification: Item Type: Circuit Breaker Material: PA66.
