LGB2B090B - 90Amp Circuit Breaker Description
LGB2B090B - 90Amp Circuit Breaker
If the breaker you're replacing is marked LGB2B090B, start by matching the complete specification set. This 90A, 2-pole LGB G-frame circuit breaker is designed for compatible low-voltage panelboards and uses a thermal-magnetic trip unit. Its interrupting ratings are 65 kA at 480Y/277V and 14 kA at 600Y/347V. That's useful information when identifying the breaker, but amperage and voltage alone don't establish compatibility. The panelboard must also accommodate the LGB G-frame, two-pole configuration, terminal arrangement, conductor range, and physical footprint of this specific model.
Key Features and Benefits
- 90A, 2-pole configuration for compatible low-voltage panelboards
- LGB G-frame design provides a specific frame reference when identifying the required replacement breaker
- Thermal-magnetic trip unit provides the specified overload and short-circuit protection
- UL Listed LGB frame
- Equipped with TC1GG20 load-side lugs only
- Accommodates 8–1/0 AWG copper or aluminum conductors
- Useful for maintenance and functional replacement where the panelboard requires the specified LGB2B090B configuration

Where It Works Best
The LGB2B090B 90A 2-pole circuit breaker makes the most sense in existing and legacy low-voltage panelboard applications designed around this LGB G-frame configuration. This is the type of replacement where the part number and detailed specifications deserve close attention. A breaker can be rated 90 amps and still be wrong for the equipment if the remaining characteristics don't match.
