LGB2B025B - 25Amp Circuit Breaker

LGB2B025B - 25Amp Circuit Breaker

The LGB2B025B is a 25A, 2-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 480Y/277V and 14 kA at 600Y/347V. If you're replacing a breaker in an existing panel, the 25-amp rating is an obvious place to start—but don't stop there. The two-pole configuration, frame, voltage ratings, lugs, conductor range, and physical dimensions all help determine whether this breaker actually belongs in the equipment.

Key Features and Benefits

• 25A, 2-pole configuration for compatible low-voltage panelboards
• LGB G-frame design gives you a specific frame reference when identifying the correct breaker
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection
• UL Listed LGB frame
• Uses TC1Q1 load-side lugs only
• Accepts 14–10 AWG copper or aluminum conductors
• Useful for maintenance and functional replacement where the original electrical and physical configuration needs to be maintained

Where It Works Best

The LGB2B025B 25A 2-pole circuit breaker is best suited to existing and legacy low-voltage panelboard equipment designed for this particular LGB G-frame configuration. It's especially relevant for maintenance jobs where the objective is to preserve the panelboard's required breaker arrangement rather than change it.

Start by checking what's already installed. Does the application call for a 25A, 2-pole LGB G-frame breaker with a thermal-magnetic trip? If so, move on to the voltage and interrupting requirements. The LGB2B025B is rated 65 kA at 480Y/277V and 14 kA at 600Y/347V.
