ABB / General Electric THQL32045 Miniature Circuit Breaker

It is compatible with 3-phase GE A-Series Panelboards and 3-phase GE PowerMark Gold Load Centers. Because it is a 3-pole breaker, it requires three adjacent 1-inch spaces on a 3-phase busbar.

No. ABB acquired GE Industrial Solutions, so this breaker may arrive with either ABB or GE branding. Both are manufactured to the same specifications and are fully interchangeable.

Yes, GE THQL breakers are HACR rated. This makes them approved for use with heating, air conditioning, and refrigeration equipment that requires branch circuit protection with an HACR designation.

The box lugs are dual-rated for both copper (Cu) and aluminum (Al) conductors, accepting wire gauges from 8 AWG up to 3 AWG.

The THQL32045 uses a fixed LI (Long-Time and Instantaneous) trip function. The thermal element (Long-Time) protects against sustained overloads, while the magnetic element (Instantaneous) trips immediately during a short circuit.

It utilizes a standard plug-in connection. The breaker snaps directly onto the bus tabs of compatible GE load centers without requiring any mounting screws or bolted hardware.

This breaker has an interrupting rating of 10kAIC at 240VAC. It must not be used in applications where the available short-circuit current exceeds 10,000 amps unless it is part of an approved series-rated system.
