ABB / General Electric THQP225 Miniature Circuit Breaker

THQP breakers are 1/2-inch wide per pole, designed to save space in compatible panels. THQL breakers are standard full-size breakers measuring 1 inch wide per pole. You can only install THQP breakers in GE load centers that explicitly permit half-size breakers on the panelboard label.

As a 2-pole thin breaker, the THQP225 requires two 1/2-inch spaces. This takes up a total of 1 inch of physical space in a compatible GE load center, which is half the space of a standard 2-pole THQL breaker.

No. While it is designed for GE PowerMark Gold and Plus load centers, it will only fit in specific panel slots designed for 1/2-inch breakers. Check your panel diagram to ensure it accepts THQP breakers and to identify the correct mounting positions.

Yes, GE THQP circuit breakers are HACR rated. This makes them suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific safety listing.

For the box lug terminals, the manufacturer specifies a tightening torque of 35 in-lb for 10 AWG wire and 40 in-lb for 8 AWG wire. Always verify the exact torque requirements printed directly on the breaker label before installation.

You should only use breakers explicitly listed on your load center label. While some UL-Classified breakers are approved for certain GE panels, using the genuine GE THQP series ensures full compliance and proper fitment in panels designed for 1/2-inch breakers.
