LGB3B030B - 30Amp Circuit Breaker

LGB3B030B - 30Amp Circuit Breaker

A breaker can have the right amperage and still be the wrong fit for a panelboard. That's why the LGB3B030B details matter. This 30A, 3-pole LGB G-frame circuit breaker is designed for compatible low-voltage panelboard applications and uses a thermal-magnetic trip unit. Electrical ratings include 65 kA at 480Y/277V and 14 kA at 600Y/347V. If you're maintaining existing electrical equipment, those ratings give you a useful starting point, but don't stop there.

Key Features and Benefits

• 30A, 3-pole configuration for compatible low-voltage panelboard applications
• LGB G-frame design provides an important identification point when matching an existing 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 (Cu/Al) conductors
• Well suited to maintenance and functional replacement where the equipment requires the specified LGB3B030B configuration

Where It Works Best

The LGB3B030B 30A 3-pole circuit breaker is a practical fit for existing and legacy low-voltage panelboards designed around this LGB G-frame configuration. Replacement work is where careful specification matching pays off. You aren't simply looking for another 30A breaker; you're looking for the electrical and physical configuration the equipment requires.

Start with the 30A rating and three-pole arrangement, then verify that the application calls for an LGB G-frame breaker with a thermal-magnetic trip unit. System requirements should correspond with the breaker's interrupting ratings of 65 kA at 480Y/277V and 14 kA at 600Y/347V.
