General Electric THHQL2160 Circuit Breaker

Both are 60-amp, 2-pole Q-Line breakers that fit the same 1-inch panel slots. The difference is the interrupting rating. The THHQL2160 is rated for 22kAIC, making it suitable for commercial or high-fault residential applications, while the standard THQL2160 is rated for 10kAIC.

The load lugs on this 60-amp breaker accept 8 AWG to 3 AWG copper or aluminum wire. Always verify your specific wire gauge requirements against the National Electrical Code (NEC) for your installation.

This plug-in breaker is designed for use in GE Power Mark Gold load centers and AQ lighting panels. Because it is a full-size Q-Line breaker, it requires two standard 1-inch spaces on the panel bus.

You cannot directly substitute a THHQL breaker with a THQP slim breaker unless your panel label explicitly permits half-inch THQP breakers in those specific bus positions. Furthermore, THQP breakers are typically only rated for 10kAIC, which will not meet the 22kAIC fault current requirement that the THHQL2160 fulfills.

Yes, it serves as a direct replacement for older 60-amp, 2-pole GE Q-Line plug-in breakers that require a 22kAIC rating. It maintains the same 2-inch overall footprint and plug-in connection for compatible GE load centers.

It utilizes a thermal-magnetic trip unit. The thermal bimetal component provides long-time protection against sustained overloads, while the magnetic element delivers instantaneous protection against short circuits.
