LGB1B030B - 30Amp Circuit Breaker

LGB1B030B - 30Amp Circuit Breaker

The LGB1B030B 30A 1-pole circuit breaker is designed for your compatible low-voltage panelboards that use the LGB G-frame configuration. It has a thermal-magnetic trip unit and an interrupting rating of 65 kA at 277V and 14 kA at 347V. For maintenance work on an existing panel, those details matter. A breaker can have the right amperage and still be the wrong fit if the frame, trip type, connections, or electrical ratings don't match.

Key Features and Benefits

• 30A, 1-pole configuration for compatible single-pole panelboard applications
• LGB G-frame design provides an important reference point when checking physical and equipment compatibility
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection characteristics
• UL Listed LGB frame for applications requiring this listing
• TC1Q1 load-side lugs only for the specified connection arrangement
• Accepts 14–10 AWG copper or aluminum wire
• Well suited to maintenance and functional replacement in compatible existing panelboard equipment

Where It Works Best

The LGB1B030B is a practical choice for maintaining existing and legacy low-voltage panelboard equipment designed around a 30A, single-pole LGB G-frame breaker. This is the kind of replacement where matching the details is more useful than simply looking at the amperage stamped on the breaker.
