ABB / General Electric THQL2160 Miniature Circuit Breaker

Yes. Following ABB's acquisition of GE Industrial Solutions, the THQL series continues under the ABB brand. Both versions share the exact same physical dimensions, UL listings, and catalog numbers.

No. Although the THQL2160 uses a standard 1-inch format, it is only UL listed for use in approved GE and ABB load centers, such as Q-Line, PowerMark Gold, and ReliaHome. Installing it in competing panel brands violates safety codes and voids the panel listing.

Yes. This breaker is HACR rated, certifying it for safe use with heating, air conditioning, and refrigeration equipment that requires a 60-amp branch circuit.

They share the same physical dimensions and trip characteristics, but differ in interrupting capacity. The standard THQL2160 provides a 10kAIC rating, while the THHQL2160 is a high-interrupting variant rated at 22kAIC for locations with higher available fault current.

Yes. If you are using the THQL2160 as a back-fed main breaker in a load center, the National Electrical Code (NEC) requires it to be secured with a mechanical hold-down bracket, such as a THQLRK series retainer kit, so it cannot be inadvertently pulled off the bus bar.

No. THQP breakers have a narrow half-inch profile. The THQL2160 is a standard full-size breaker requiring two full 1-inch spaces (2 inches total). It cannot be installed in a half-inch tandem slot unless two consecutive full spaces are available.

Yes. The box lugs are AL/CU rated, meaning they safely accept both aluminum and copper conductors. When using aluminum wire, ensure you apply an approved antioxidant compound and follow proper torque specifications.

Yes. The THQL series is the direct modern replacement for obsolete GE TQL and TQAL plug-in circuit breakers, provided your load center allows a 60-amp branch circuit in that position.
