LGB2B080B - 80Amp Circuit Breaker

LGB2B080B - 80Amp Circuit Breaker

The LGB2B080B is an 80A, 2-pole LGB G-frame circuit breaker designed for compatible low-voltage panelboard applications. It combines a thermal-magnetic trip unit with interrupting ratings of 65 kA at 480Y/277V and 14 kA at 600Y/347V. When you're replacing a breaker in an existing panel, the 80-amp rating is an obvious checkpoint, but it's only the beginning. The two-pole arrangement, LGB frame, trip type, interrupting capacity, terminals, wire range, and physical size must all match the equipment.

Key Features and Benefits

• 80A, 2-pole configuration for compatible low-voltage panelboard applications
• LGB G-frame design provides an important identification point when matching existing equipment
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection
• UL Listed LGB frame
• Uses TC1GG20 load-side lugs only
• Accepts 8–1/0 AWG copper or aluminum conductors
• Appropriate for maintenance and functional replacement where the panelboard calls for this particular electrical and physical configuration

Where It Works Best

The LGB2B080B 80A 2-pole circuit breaker fits applications involving existing and legacy low-voltage panelboards designed for this specific LGB G-frame breaker configuration. In this kind of maintenance work, small specification differences matter. A breaker with the same amp rating isn't automatically the right match.

When the amperage, pole count, LGB frame, trip type, interrupting ratings, lug configuration, conductor range, and dimensions match the panelboard requirements, you have a solid basis for evaluating the LGB2B080B as the correct form, fit, and functional replacement.
