LGB1B045B - 45Amp Circuit Breaker Description
LGB1B045B - 45Amp Circuit Breaker
The LGB1B045B is a 45A, 1-pole LGB G-frame circuit breaker for compatible low-voltage panelboards. It uses a thermal-magnetic trip unit and has interrupting ratings of 65 kA at 277V and 14 kA at 347V. If you're replacing a breaker that's already in service, don't judge the match by amperage alone. A 45-amp rating gets you started.
Key Features and Benefits
- 45A, single-pole design for compatible low-voltage panelboard applications
- LGB G-frame configuration helps narrow down the correct physical and functional match
- 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 wire
- A practical choice for maintaining the required breaker configuration in compatible existing equipment

Where It Works Best
The LGB1B045B 45A circuit breaker is best suited to existing and legacy low-voltage panelboard equipment that calls for this particular LGB G-frame configuration. It's especially relevant when the job is to keep an existing electrical system in service with the correct breaker type rather than changing the equipment configuration.
