LGB2B030B - 30Amp Circuit Breaker

LGB2B030B - 30Amp Circuit Breaker

The LGB2B030B is a 30A, 2-pole LGB G-frame circuit breaker for compatible low-voltage panelboards. It uses a thermal-magnetic trip unit and is rated 65 kA at 480Y/277V and 14 kA at 600Y/347V. If you're replacing a breaker already in a panel, those are some of the first specifications to check. But don't rely on the 30-amp rating alone. The two-pole configuration, LGB frame, trip type, lug arrangement, wire range, and physical footprint all matter in determining whether you've got the right match.

Key Features and Benefits

• 30A, 2-pole configuration for compatible low-voltage panelboard applications
• LGB G-frame design provides a useful frame reference when matching the breaker to existing equipment
• 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 panelboard needs to retain the specified breaker arrangement

Where It Works Best

The LGB2B030B 30A 2-pole circuit breaker is best suited to existing and legacy low-voltage panelboard equipment designed around this particular LGB G-frame configuration. It's the kind of replacement where a careful specification check pays off. A breaker can share the same amp rating and still differ in several details that matter to the application.
