GE THQB2180 80A 2 Pole 120/240V AC Circuit Breaker

GE THQB2180 80 A breaker for lighting panels

The GE THQB2180 is a miniature circuit breaker rated at 80 A for 120/240 V AC systems. It uses a bolt-on mounting style suited for load centers and lighting panels. The two-pole design provides standard overcurrent protection for single-phase installations. UL listing confirms compliance with applicable safety standards.

10 kA interrupting rating at 120/240 V AC

The maximum AIR rating is 10 kA at 120/240 V AC, which determines whether the breaker can safely clear faults in a given panel. Installers must verify that the available fault current at the point of installation does not exceed this value. The breaker carries no DC voltage rating and is not rated for DC applications. Correct matching of interrupting capacity is essential for code compliance.

80 A continuous capacity with 6 AWG to 1/0 AWG lugs

The 80 A frame handles sustained loads up to its rating when wired with conductors between 6 AWG and 1/0 AWG. The 100 A frame size provides physical space for the larger lugs but does not increase the breaker's ampere rating. Circuits requiring more than 80 A or a higher interrupting rating will need a different device.
