Description

Designed for 20-amp commercial circuits, this single-pole unit delivers critical 5mA ground fault protection. It helps facility managers maintain strict NEC compliance for receptacles located near water sources or in damp areas. The bolt-on configuration fastens firmly into Eaton Pow-R-Line panelboards, preventing loose connections in high-vibration environments. It replaces the legacy QBGF1020 configuration.

Product FAQs

5 answers
What is the ground fault trip sensitivity for the QBGFT1020?

This breaker is a Class A GFCI [1.1.1] with a 5 mA trip threshold, designed specifically for personnel protection.

Which panelboards accept the QBGFT1020 breaker?

It installs directly into Eaton Pow-R-Line panelboards, including the PRL1a, PRL2a, and PRL3X series, that are configured for Quicklag bolt-on branch circuit breakers.

Does the QBGFT1020 replace any older Cutler-Hammer part numbers?

Yes, it is the direct replacement for the legacy QBGF1020 and QB1020GF models. The updated QBGFT series features the self-test capabilities required to meet modern UL 943 standards.

How do I terminate the neutral for this GFCI breaker?

The QBGFT1020 is equipped with a pigtail neutral wire. This pigtail must be securely landed on the panelboard neutral bus for the ground fault circuit interrupter and self-test functions to operate properly.

Is the QBGFT1020 suitable for HVAC applications?

Yes, like all Eaton Quicklag miniature circuit breakers in this amp range, it is HACR rated and approved for use with heating, air conditioning, and refrigeration equipment.
