4. Operating the Circuit Breaker
The BRH2125 circuit breaker features a toggle switch for manual operation and a common trip mechanism for safety.

This close-up image displays the operating labels on the circuit breaker, clearly showing the 'On/I' and 'Off/O' positions for each pole, along with the '125' amp rating. The 'Common Trip' label is also visible, indicating that both poles trip simultaneously.
د کار ځایونه:
- پر (زه): Pushing the toggle switch to the 'On/I' position connects power to the circuit.
- بند (O): Pushing the toggle switch to the 'Off/O' position disconnects power from the circuit.
- بند شوی: If an overload or short circuit occurs, the breaker will automatically move to a central, tripped position (often indicated by the toggle being between ON and OFF, or fully OFF with a red indicator). This is the 'Common Trip' feature, meaning both poles disconnect simultaneously.
د ټریپ شوي بریکر بیا تنظیم کول:
