HGB3B110B - 110Amp Circuit Breaker

HGB3B110B - 110Amp Circuit Breaker

When you’re matching a breaker for an existing panelboard, the nameplate details have to line up. The HGB3B110B is a 110-amp, 3-pole HGB G-frame circuit breaker designed for compatible low-voltage panelboard applications. If HGB3B110B is the catalog number on your replacement list, the combination of 110 amps, three poles, HGB frame construction, thermal-magnetic protection, interrupting capacity, and lug configuration gives you the core information needed to determine whether it belongs in the application.

Key Features and Benefits

• 110A, 3-pole configuration: Designed for compatible electrical applications requiring a 110-amp, three-pole breaker.
• Thermal-magnetic trip protection: Responds to prolonged overloads as well as short-circuit conditions.
• HGB G-frame construction: Made for compatible low-voltage panelboard installations using this frame style.
• TC1GG20 load-side lugs: Gives installers a clearly identified connection arrangement for this model.
• Cu/Al conductor capability: Accepts 8 AWG through 1/0 AWG copper or aluminum wire.

Material Compliance and Certifications

The HGB3B110B is UL Listed, an important specification when checking a breaker against the requirements of the panelboard and electrical system where it will be installed.

Where It Works Best

The HGB3B110B makes the most sense in compatible low-voltage panelboards and commercial or industrial electrical distribution systems that specifically call for a 110A, 3-pole HGB G-frame breaker with thermal-magnetic protection.
It can be particularly useful during maintenance and replacement work, where matching the breaker already specified for the equipment is more important than simply finding another 110-amp unit. The TC1GG20 load-side lugs and 8 AWG to 1/0 AWG Cu/Al conductor range are worth checking closely, along with the frame size and interrupting ratings.
