ABB / General Electric THHQL2125 Miniature Circuit Breaker

Both are 1-inch wide per pole Q-Line plug-in breakers that fit the same panels. The difference is the interrupting capacity. THQL breakers are rated at 10kAIC, while THHQL breakers like the THHQL2125 are rated for 22kAIC to handle higher available fault currents.

This breaker is designed for use in GE PowerMark Gold load centers, GE A-Series panelboards, and ABB ReliaHome load centers that accept 1-inch wide Q-Line plug-in breakers.

Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 25-amp, 2-pole overcurrent protection device.

The box lugs accept 14 to 8 AWG copper or 12 to 8 AWG aluminum wire. When terminating, standard torque requirements for this frame are 35 in-lb for 10 AWG wire and 40 in-lb for 8 AWG wire. Always verify exact torque values on the breaker label.

ABB acquired GE Industrial Solutions in 2018. The THHQL2125 is the exact same Q-Line circuit breaker, manufactured to the same specifications, regardless of whether it is branded as GE or ABB.

No, this is a standard thermal-magnetic circuit breaker. It provides overload and short-circuit protection but does not include ground-fault or arc-fault circuitry.
