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.

Postes opérationnels :

• SUR (I) : Pushing the toggle switch to the 'On/I' position connects power to the circuit.
• OFF (O) : Pushing the toggle switch to the 'Off/O' position disconnects power from the circuit.
• DÉBORDÉ : 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.
