Description
Providing reliable thermal-magnetic protection, the Eaton HGHB1020 is a 1-pole, 20A molded case circuit breaker. It is a core component of the Series C G-Frame lineup for commercial branch circuits. This breaker utilizes a bolt-on mechanism to install securely into Eaton Pow-R-Line 2 (PRL2) panelboards and switchboards. It accepts 14 to 1/0 AWG wire via load side lugs. With a 65kAIC rating at 120VAC, it interrupts high fault currents and is fully HACR and SWD rated.Specifications

Product FAQs
7 answersWhat panelboards accept the Eaton HGHB1020 circuit breaker?
This G-Frame breaker is designed for bolt-on installation in Eaton Pow-R-Line 2 (PRL2) panelboards, Series C panelboards, switchboards, and motor control centers.
What frame size is the HGHB1020?
The HGHB1020 is part of the Eaton Series C G-Frame family of molded case circuit breakers.
What is the difference between the Eaton HGHB1020 and the standard GHB1020?
The HGHB1020 is the high-interrupting version of the GHB1020. While the standard GHB1020 is rated for 14kAIC at 277VAC, the HGHB1020 provides an upgraded 25kAIC at 277VAC and 65kAIC at 120VAC for systems with higher fault current requirements.
Is the HGHB1020 rated for HVAC and lighting applications?
Yes, this 20-amp breaker is fully HACR rated for heating, air conditioning, and refrigeration equipment. It is also SWD (Switching Duty) rated, meaning it can be used to safely switch fluorescent lighting loads on and off.
What do the LI trip functions on the HGHB1020 indicate?
The LI designation means the breaker provides Long-Time (thermal) and Instantaneous (magnetic) trip functions. Both the thermal and magnetic trip points are fixed and cannot be adjusted in the field.
How are wire connections made on the HGHB1020?
The breaker features integrated load-side lugs that accept a wire range from 14 AWG up to 1/0 AWG. The line side uses a bolt-on connection to attach directly to the panelboard bus.
Will this breaker replace an older Cutler-Hammer HGHB1020?
Yes. Eaton acquired Cutler-Hammer, and current Eaton HGHB breakers are direct, identical replacements for legacy Cutler-Hammer models sharing the same catalog number.
