Circuit Breakers (Options, Others)

Circuit breakers (optional parts and accessories) refer to overcurrent protection devices that protect load circuits and cables from damage when the power supply is shut off. They include safety breakers, single phase 3-wire circuit breakers with open neutral protection, motor breakers, earth leakage circuit breakers, and more. Accessories include auxiliary breaker switches and ground wire terminals. Materials used include rigid PVC, with features such as excellent weather resistance, water resistance and strength. They can be used in any number of locations, including factories and offices. Circuit breakers (optional parts and accessories) must be installed correctly; failure to do so may cause loosening and fall-offs, as well as severe accidents such as overheating and burnouts. For this reason, it is necessary to know how to use these components correctly.
