Circuit Breaker for Three-Phase Panels
The GE THHQB 32020 is a bolt-on miniature circuit breaker rated at 20 A for 120/240 V AC three-phase systems. It provides high interrupting capacity protection for load centres and lighting panels in commercial or residential electrical installations.
22 kA Interrupting Rating and Screw-Clamp Terminals
The 22 kA AIR rating at 120/240 V AC allows the breaker to clear severe fault currents safely. Screw-clamp terminals accept conductors down to 14 AWG, securing connections without additional lugs or tools beyond a standard screwdriver.
Compact Bolt-On Frame Fits 60 A Bus Bars
A 60 A frame size measuring 3.3 in long, 3 in wide and 2.4 in deep mounts directly onto compatible bus bars. The toggle actuator gives clear on/off indication, while the three-pole layout occupies a single slot for balanced three-phase circuit protection.

Questions about this item
Will the screw-clamp terminals accept wire smaller than 14 AWG if I need to replace a conductor later?
The terminals are rated for a minimum wire size of 14 AWG, so smaller conductors should not be used.
Does the 22 kA interrupting rating limit how long the breaker can carry its full 20 A load continuously?
The 22 kA AIR rating is a short-circuit withstand value; it does not restrict continuous current, which remains 20 A per pole.
How much heat does the three-pole unit add to a panel when it runs all day at 20 A per phase?
With bolt-on mounting and a 60 A frame, the breaker dissipates normal load heat inside the enclosure; no forced-air cooling is required.
