THQP250 - 50Amp Circuit Breaker

THQP250 - 50 Amp Circuit Breaker

The THQP250 is a 50-amp, 2-pole plug-on circuit breaker designed for dependable overload and short-circuit protection in your residential and light commercial electrical systems. Built as part of the trusted Q-Line THQP series, this "thin" space-saving breaker helps you to maximize panel capacity without sacrificing performance. Its compact profile makes it a smart solution for load centers where every inch of space matters, especially during upgrades, remodels, or panel expansions. Featuring an internal common trip design, the THQP250 disconnects both poles simultaneously for added safety and code compliance in 120VAC applications. HACR-rated and engineered for consistent operation, this molded-case circuit breaker is commonly used in HVAC systems, air conditioning equipment, subpanels, and other demanding branch-circuit applications where reliable protection is essential.
