LGB1B110B - 110Amp Circuit Breaker

LGB1B110B - 110Amp Circuit Breaker

The LGB1B110B is a 110A, 1-pole LGB G-frame circuit breaker for compatible low-voltage panelboards. Inside, it uses a thermal-magnetic trip unit. Its documented interrupting ratings are 65 kA at 277V and 14 kA at 347V. Those specifications give you a good starting point when you're trying to match a breaker already installed in a panel, but there's more to check.

This particular LGB breaker has TC1GG20 load-side lugs only and accommodates 8–1/0 AWG copper or aluminum conductors. These breakers are built to last, but choosing one for an existing electrical system should still come down to the specifications.

Key Features and Benefits

• 110A, single-pole configuration for compatible low-voltage panelboard applications
• LGB G-frame design gives technicians a specific frame configuration to check against existing equipment
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection
• UL Listed LGB frame
• Uses TC1GG20 load-side lugs only
• Accommodates 8–1/0 AWG copper or aluminum conductors
• Useful for maintenance and replacement work where the required breaker configuration needs to remain consistent

Where It Works Best

The LGB1B110B 110A circuit breaker is intended for existing and legacy low-voltage panelboard equipment that requires this LGB G-frame configuration. For that type of maintenance work, the question isn't simply, "Is this a 110-amp breaker?" The better question is, "Do all the important specifications match?"

Check the 110A rating and single-pole configuration first. Then confirm that the equipment requires an LGB G-frame breaker with a thermal-magnetic trip. The interrupting capacity must match as well—the LGB1B110B is rated 65 kA at 277V and 14 kA at 347V.
