ABB / General Electric THHQB32060 Miniature Circuit Breaker

No. The THHQB32060 is a bolt-on breaker designed strictly for commercial and industrial panelboards like the GE A-Series, AQ, and ReliaGear lines. Residential PowerMark panels require plug-in circuit breakers, such as the THQL series.

The difference lies in their short-circuit interrupting capacity. THQB breakers are rated at 10kAIC, while THHQB models like this one provide a higher 22kAIC rating. Both share the identical bolt-on mounting configuration and physical dimensions.

You may receive a unit branded as either General Electric or ABB. Following ABB's acquisition of GE Industrial Solutions, identical Q-Line circuit breakers are distributed under both brand names depending on the manufacturing date.

Yes. This breaker carries an official HACR rating, meaning it is approved for the unique inrush currents and continuous loads associated with motor-driven heating, air conditioning, and refrigeration equipment.

Yes. This thermal magnetic breaker has no directional line or load restrictions and is suitable for reverse feed applications. Because it physically bolts directly to the panel bus, it inherently satisfies National Electrical Code fastening requirements for back-fed main breakers without requiring an additional hold-down kit.

Yes. The breaker features an internal common trip mechanism. If an overload or short circuit occurs on any single phase, all three poles will open simultaneously. This provides critical safety by preventing single-phasing damage to three-phase equipment.
