Product FAQs

5 answers
What type of electrical panels are compatible with the GFXB120B2?

The GFXB120B2 features a plug-on mounting design and is specifically engineered for use in Eaton Type BR load centers.

What is the difference between the GFXB120B2 GFEP breaker and a standard GFCI breaker?

The GFXB120B2 provides Ground Fault Equipment Protection (GFEP) with a 30mA trip threshold, designed to protect machinery and equipment from low-level faults. Standard GFCI breakers trip at 5mA and are intended for personnel protection.

How do I connect the neutral for the GFXB120B2?

The GFXB120B2 features a pigtail neutral connection. The attached white pigtail wire must be routed and secured directly to the neutral bus bar in your load center to ensure the ground fault protection operates correctly.

Does the GFXB120B2 provide a visual indication when it trips?

Yes, this breaker is equipped with a visual GFI indicator to help easily identify when a trip event was caused by a ground fault.

What specific trip functions are included in the GFXB120B2?

This breaker features Long-Time, Instantaneous, and Ground Fault (LIG) trip functions. The thermal-magnetic mechanism handles standard overload and short-circuit protection, while the GFEP component monitors for 30mA ground faults.
