ABB / General Electric THQP2150 THQP250 - 50A 2 Pole Miniature Circuit Breaker

THQP breakers are half-size or slimline breakers, measuring 1/2 inch wide per pole. THQL breakers are standard full-size breakers, measuring 1 inch wide per pole. The THQP2150 is a 2-pole breaker that takes up 1 inch of total panel space, whereas a 2-pole THQL breaker requires 2 inches. You can only install THQP breakers in GE load centers that are explicitly designed to accept them.

No. While it is designed for GE Q-Line and PowerMark Gold load centers, THQP half-size breakers can only be installed in panel slots specifically designated for tandem or thin breakers. Check your panelboard label to confirm it accepts THQP breakers before installation.

Yes. The THQP250 and THQP2150 are alternate catalog numbers for the exact same 50A, 2-pole, half-size GE circuit breaker. They share identical physical dimensions, trip functions, and electrical ratings.

The box lug terminals on the THQP2150 are designed to accept 8 AWG to 4 AWG copper or aluminum wire. Always verify the correct wire gauge for your specific 50A application based on current National Electrical Code requirements and local guidelines.

Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration motor loads that require a 50A, 2-pole overcurrent protection device.

ABB acquired GE Industrial Solutions in 2018. As a result, newly manufactured THQP breakers may feature ABB branding, GE branding, or a combination of both. The breaker itself remains identical in form, fit, and function regardless of the label.
