Description
Part of the Quicklag family, the Eaton QBHGF2020 is a 2-pole, 20A miniature breaker. It provides essential 5mA ground fault and thermal-magnetic protection for 120/240VAC commercial systems. The bolt-on mounting style guarantees a secure fit within Eaton Pow-R-Line panelboards. It replaces older Cutler-Hammer breakers and is officially superseded by the modern QBHGFT2020 self-testing model. Boasting a 22kAIC interrupting capacity, it safely manages severe electrical faults.Specifications

Product FAQs
5 answersWhat panelboards are compatible with the QBHGF2020?
This bolt-on breaker is designed for use in Eaton Pow-R-Line commercial panelboards, such as the PRL1a and PRL1X series. It is not compatible with standard residential plug-on load centers.
What is the ground fault trip threshold for the QBHGF2020?
This breaker provides Class A personnel protection with a 5mA ground fault trip threshold. For 30mA equipment protection, an EP suffix breaker is required.
What is the difference between the Eaton QBGF2020 and QBHGF2020?
The difference is the interrupting rating. The QBGF2020 is rated at 10kAIC, while the QBHGF2020 has a higher interrupting rating of 22kAIC. Both are 20A, 2-pole, bolt-on GFCI breakers.
How is the neutral connected on the QBHGF2020?
This breaker features a pigtail neutral connection. The coiled white wire must be connected directly to the panelboard neutral bar for the ground fault protection to function correctly.
Does the QBHGF2020 provide arc fault protection?
No, this is a dedicated Ground Fault Circuit Interrupter (GFCI) breaker. It does not provide arc fault protection or dual-function capabilities.
