LGB1B020B - 20Amp Circuit Breaker

LGB1B020B - 20Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, the little details matter. The LGB1B020B is a 20A, 1-pole LGB G-frame circuit breaker with a thermal-magnetic trip unit. It's made for compatible low-voltage panelboard equipment and is UL Listed.

Key Features and Benefits

• 20A, 1-pole design: For compatible applications that call for a 20-amp, single-pole breaker.
• LGB G-frame: An important identifier when matching a breaker to existing panelboard equipment.
• Thermal-magnetic trip unit: Uses the specified thermal-magnetic protection design.
• UL Listed: The manufacturer identifies the LGB frame as UL Listed.
• Load-side lugs only: A connection detail worth checking carefully against the existing breaker.
• 14–10 AWG Cu/Al wire range: Accommodates copper or aluminum conductors within the stated range.
