The SIWOB2S-63 series small circuit breaker is suitable for circuits with rated voltage up to 400V and rated current up to 63A. It is used for overcurrent protection of line facilities and electrical equipment in buildings and similar places, and can also be used for infrequent making and breaking operations.

1. Precision Bimetal is used as thermal overload current release to provide delay protection for the line;
2. Electromagnetic high-speed release with solenoid for short circuit protection of circuits:
To prevent overloading of the distribution system (if there is no short circuit fault in the circuit, overheating and overloading may occur that may damage the wiring):
Prevent short circuits in the distribution system and electrical devices, such as those caused by circuit faults or incorrect connections.
3. Circuit breakers have high short-circuit breaking capacity;
When overcurrent occurs in the circuit and the circuit breaker trips, the handle is in the open position, prompting the user to quickly troubleshoot.
