Square D QOB120GFI1200 GFCI Miniature Circuit Breaker

This bolt-on breaker is specifically designed for Square D NQ and NQOD panelboards. Because it requires a bolted connection to the bus bar, it cannot be installed in standard QO residential load centers that use plug-on mounting.

The 1200 suffix indicates the inclusion of a factory-installed 1A auxiliary switch. This allows the breaker to be wired to remote monitoring systems or control circuits to indicate whether the breaker contacts are open or closed.

This breaker is equipped with a pigtail neutral wire. During installation, the pigtail must be routed and secured directly to the neutral bus bar in the panelboard to power the internal ground fault circuitry.

It provides Class A ground fault protection. The internal circuitry is calibrated to trip and interrupt power if it detects a ground fault leakage current of 6 mA or greater, protecting personnel from electrical shock.

Yes, it includes the Square D Visi-Trip feature. When the breaker trips due to an overload, short circuit, or ground fault, a bright red indicator appears in the window to help you quickly identify the faulted circuit in a crowded panel.

Yes, it will physically fit and provide the exact same 20A overcurrent and ground fault protection. However, the QOB120GFI1200 includes an extra auxiliary switch. If your system does not require remote status monitoring, you can simply cap off the auxiliary leads and use it as a standard breaker.
