General Electrics THHQB1115AF2 - 15 A, 1-Pole Bolt-On Circuit Breaker | AmpState

General Electrics THHQB1115AF2 — a 15A, 1-pole bolt-on molded case circuit breaker designed to provide robust branch circuit protection in panelboards and load centers. Listed by AmpState, this unit pairs precise protection with straightforward installation, making it a dependable choice for a wide range of electrical setups.

Key to its reliability is the secure bolt-on mounting, which delivers a rigid, vibration-resistant bus connection. In environments where equipment vibration or movement is a concern, this design helps maintain consistent electrical contact and minimizes the risk of loose connections that can lead to nuisance trips or heat buildup.

The breaker features a thermal-magnetic trip unit, offering stable, repeatable protection across varying loads and temperatures. The thermal element responds to overloads by slowly opening the circuit, while the magnetic element provides fast, decisive action during short-circuit events. This combination delivers predictable trip characteristics, helping protect wiring and connected devices without unnecessary interruptions.

Designed for compatibility with matching GE OEM load centers and panelboards, the THHQB1115AF2 ensures a smooth, integrated fit. This compatibility reduces installation guesswork and helps maintain uniform protection performance across your system. It’s suitable for residential, commercial, and light industrial applications, making it a versatile solution for lighting circuits, receptacle runs, small motor loads, and other branch-circuit protections.
