Overview

The ABB THQP145 (SKU: THQP145) is a 1-pole, 45 Ampere circuit breaker designed for 120/240V applications with a 10kAIC interrupting rating. Engineered as part of ABB's Q Line series, this breaker features a compact 1/2-inch width—half the size of standard 1-inch breakers—enabling significant space and cost savings in load centers. The THQP145 is ideal for residential and light commercial installations where panel space is constrained, such as in multi-family housing, small offices, or renovation projects. Its thermal-magnetic trip mechanism provides reliable overcurrent protection, while the quick-make/quick-break operation ensures safe and consistent performance during fault conditions. The breaker uses a bolt-on mounting system for secure attachment to load center bus bars, ensuring stable electrical connections. Compatible with ABB and GE by ABB PowerMark™ load centers, the THQP145 maintains full UL compliance and supports reverse feed applications. With a wire range of #14-8 AWG copper or #12-8 AWG aluminum, it accommodates standard residential wiring practices. The THQP series, including the THQP145, is designed for contractors and homeowners prioritizing efficiency, cost-effectiveness, and modern electrical distribution needs without sacrificing performance or safety.
