Description

Rated for 10 kAIC at 120/240VAC, this 1-pole, 20A bolt-on circuit breaker from Eaton's Quicklag series delivers essential equipment protection. It combines standard thermal-magnetic overcurrent defense with a 30mA ground fault equipment protection (GFEP) threshold, preventing damage from line-to-ground faults. Designed to mount into Eaton Pow-R-Line panelboards, the QB1020EP serves as a direct substitute for the legacy QBGFEP1020. It features a pigtail neutral connection and is SWD rated.

Product FAQs

5 answers
Which panelboards accept the Eaton QB1020EP circuit breaker?

The QB1020EP is a bolt-on miniature circuit breaker designed specifically for installation in Eaton Pow-R-Line panelboards.

What is the ground fault trip sensitivity of the QB1020EP?

This Ground Fault Equipment Protector (GFEP) features a 30mA trip threshold. It is designed to protect equipment from damaging line-to-ground faults, unlike Class A GFCI breakers which trip at 5mA for personnel protection.

What is the direct replacement for the legacy QBGFEP1020 breaker?

The Eaton QB1020EP serves as the direct, manufacturer-approved substitute for the obsolete Cutler-Hammer QBGFEP1020.

How is the neutral connection wired on the QB1020EP?

This breaker utilizes a pigtail neutral wire. The pigtail must be securely connected to the panelboard neutral bus bar for the ground fault equipment protection circuitry to function correctly.

Is the QB1020EP suitable for switching lighting loads?

Yes, this breaker is SWD (Switching Duty) rated, meaning it is approved for use as a switch to control fluorescent lighting circuits on a regular basis.
