GE THQB1115AF2 - 15 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The GE THQB1115AF2 is a 15A, 120V, 1-pole bolt-on molded-case circuit breaker built to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed for residential, commercial, and light industrial environments, this device blends robust construction with precise protection to keep electrical systems safe and reliable.

Why this breaker matters

• Secure bolt-on mounting — delivers a rigid, vibration-resistant bus connection that stays seated even in demanding environments, reducing loose connections and nuisance trips.
• Thermal-magnetic trip unit — combines thermal protection for prolonged overloads with instantaneous magnetic trip for rapid fault clearance, ensuring stable, repeatable protection performance.
• OEM-compatible design — engineered to pair with matching GE OEM loadcenters and panelboards, offering a seamless, reliable fit and straightforward replacement in existing systems.
• Versatile across sectors — ideal for residential circuits, small commercial feeders, and light industrial drop lines where a single-pole 120V protection device is needed.
• Genuine GE reliability — part number THQB1115AF2, backed by GE’s engineering standards and built for long-term service life in real-world installations.

What problems does it solve?

• Prevents damage from overcurrent and short circuits on individual 120V branch circuits, helping to protect wiring, devices, and downstream equipment.
• Provides a quick, safe reset after a trip, minimizing downtime and maintenance complexity compared with fuse-based setups.
• Eliminates vibration-induced connection issues with its bolt-on design, reducing intermittent faults caused by loose bus connections.

Who is this ideal for?

• Homeowners upgrading or stocking GE-compatible replacement parts for existing panelboards and loadcenters.
• Electrical pros performing routine panel maintenance or new installations in light commercial or residential settings.
• Installers seeking a compact, reliable, single-pole protection option for 120V circuits requiring precise, repeatable tripping behavior.

Installation and use tips

Install in compatible GE panelboards or loadcenters that match the THQB family. Ensure proper torque on mounting hardware to maintain the rigid bus connection, and verify circuit loading stays within the 15A rating to prevent nuisance trips. Use this breaker to shield branch circuits feeding lighting, outlets, or small equipment on 120V systems, delivering fast fault clearance while keeping service interruptions brief and predictable.
