Square D QO360 circuit breaker is ideal for safeguarding distribution panels, control cabinets & load centres against overloads and short circuits by quickly interrupting faulty currents.
Working Mechanism:
- The thermal tripping mechanism of the circuit involves a bimetallic strip. As the current flowing through the circuit persist above the breaker's designated current limit for an extended duration, the bimetallic strip experiences heating due to the heating effect. As a consequence of the distinct expansion rates between its two metal layers, the strip undergoes flexion, resulting in the disengagement of the latch responsible for keeping the contacts closed. This motion triggers the divergence of the contacts, effectively interrupting the circuit connection and isolating the faulty segment from the power source.
Features:
- Square D QOB220 circuit breaker has a VisiTrip indicator that provides a visual indication of tripping and interruption in the circuit.
- This miniature circuit breaker has a reliable trip-free toggle mechanism, ensuring the breaker cannot be held in the ON position during a fault for operational safety.
- It comes with a positive handle indication to easily identify the operation status.
- This Square D mini breaker provides a 10kAIC breaking capacity for high tripping protection of the circuit.
Compatible Accessories:
- Square D QO1HPL Padlock Attachment: It is used to interlock and secure Square D circuit breaker handles while accidentally tripping and limiting access to the breaker.
