LGB2B110B - 110Amp Circuit Breaker

LGB2B110B - 110Amp Circuit Breaker

Need to match a 110A, 2-pole breaker in an existing low-voltage panelboard? The LGB2B110B is an LGB G-frame circuit breaker with a thermal-magnetic trip unit, rated 65 kA at 480Y/277V and 14 kA at 600Y/347V. Those electrical ratings are key identification points, but they're only part of the compatibility check. The breaker must also match the required frame, pole arrangement, lug configuration, conductor size, and available physical space. That's especially important when you're maintaining legacy electrical equipment and need a functional replacement, not something that's merely similar on paper.

Key Features and Benefits

• 110A, 2-pole configuration for compatible low-voltage panelboard applications
• LGB G-frame construction gives technicians and buyers a clear frame reference when matching existing equipment
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection
• UL Listed LGB frame
• Includes TC1GG20 load-side lugs only
• Accommodates 8–1/0 AWG copper or aluminum conductors
• Suitable for maintenance and functional replacement when an existing panelboard requires this particular LGB breaker configuration

Where It Works Best

The LGB2B110B 110A 2-pole circuit breaker is especially relevant when servicing existing and legacy low-voltage panelboards that require this LGB G-frame configuration. When replacing breakers, check several details before deciding a breaker is a match.

First, confirm the basic configuration: 110 amps, two poles, LGB G-frame, and thermal-magnetic trip. Next come the system requirements. The LGB2B110B has an interrupting rating of 65 kA at 480Y/277V and 14 kA at 600Y/347V, so the application must match those ratings.
