ABB / General Electric THQL32100 Miniature Circuit Breaker

The required tightening torque depends on the installed wire gauge. Apply 50 in-lb for #3 to 1/0 AWG conductors, and 45 in-lb for #6 to #4 AWG conductors. The box lug terminals are rated to accept both copper and aluminum wiring.

GE Q-Line breakers are 1 inch wide per pole. The THQL32100 will occupy three consecutive 1-inch spaces on a compatible 3-phase panel bus.

This plug-on breaker is designed for use in 3-phase GE Q-Line load centers, GE A-Series lighting panels, and modern ABB ReliaHome distribution panels that accept THQL frame types.

Yes, the THQL32100 carries an HACR (Heating, Air Conditioning, and Refrigeration) rating. This ensures it is tested to safely handle the inductive loads and inrush currents generated by commercial HVAC compressors and motors.

The choice depends on the available fault current at your panel. The THQL32100 provides a 10kAIC rating at 240VAC. If your electrical system requires a higher 22kAIC interrupting capacity, you must use the THHQL32100 instead.

Yes. The internal common trip mechanism ensures that if an overload or short circuit occurs on any single pole, all three poles will trip simultaneously to safely disconnect the entire 3-phase load.

Yes, this standard thermal-magnetic breaker is non-directional and is suitable for reverse-feed applications. Always verify that back-feeding is permitted by your specific panelboard labeling and local NEC guidelines.
