General Electric THHQB1120AF is a 20A, 1-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built for residential, commercial, and light industrial applications, this unit combines rugged mounting with precise protective action to keep electrical systems safe and running smoothly.
Perfect for real-world use
Why this THHQB1120AF stands out: the bolt-on mounting delivers a sturdier bus connection than plug-in options, reducing the risk of loose connections that can cause nuisance trips. The combination of a thermal and magnetic trip mechanism provides both predictable overload protection and immediate short-circuit interruption, helping to safeguard wiring, devices, and downstream equipment.
