ABB / General Electric THHQB2130 Miniature Circuit Breaker

This bolt-on breaker installs directly onto the bus connections of GE A-Series panelboards and ABB ReliaGear RQ lighting panels. It cannot be used in standard residential load centers that require plug-in style breakers.

Yes. The THHQB2130 shares the exact same physical dimensions and bolt-on mounting configuration as the THQB2130. The key difference is the THHQB series provides a higher interrupting capacity of 22kAIC compared to the 10kAIC rating of the THQB. Always ensure the replacement meets your panel's short-circuit requirements.

The "H" designates this as a high-interrupting capacity model within the Q-Line breaker family. While a standard THQB breaker offers a 10kAIC rating, the THHQB delivers enhanced protection with a 22kAIC rating for commercial and industrial applications.

Yes. The manufacturer specifies that the THHQB2130 is suitable for reverse feed applications. This is commonly required when the breaker is functioning as a main disconnect or handling backfed inputs in the panelboard.

Yes, the THHQB2130 carries a HACR rating, certifying it for safe use with the motor group loads typically found in heating, air conditioning, and refrigeration systems.

No. The THHQB2130 utilizes a bolt-on connection specifically for commercial panelboards. It is not physically compatible with load centers designed for plug-in THQL or THHQL breakers.
