GE THQB1150 - 50 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Introducing the GE THQB1150—a 50A, 120V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for steady performance, this unit combines secure bolt-on mounting with a thermal-magnetic trip mechanism to provide stable, repeatable protection for your electrical system.

• Secure bolt-on mounting: provides a rigid, vibration-resistant connection to the bus, reducing loosening and arcing in active panels.
• Thermal-magnetic trip unit: delivers precise overload protection (thermal) and fast short-circuit response (magnetic) for predictable, nuisance-free trips when you need them most.
• OEM compatibility: engineered to integrate smoothly with GE panelboards and load centers, ensuring reliable performance without compatibility surprises.
• Versatile applications: ideal for residential, commercial, and light industrial environments where a robust 50A, 120V single-pole breaker is required.
• Specified for the task: part number THQB1150, 1-pole, bolt-on, molded case circuit breaker designed for branch circuit overcurrent and short-circuit protection.

Use cases include upgrading or replacing a worn breaker in GE-compatible panels, protecting high-draw 120V branch circuits in homes, shops, or small offices, and configuring reliable protection for subcircuits where dependable tripping behavior is critical. The combination of bolt-on stability and a thermal-magnetic trip curve helps minimize downtime and protect wiring, devices, and loads from damage due to overcurrent or short circuits.

Compatibility & installation considerations

The THQB1150 is designed for panelboards and load centers that accept bolt-on molded case breakers. Ensure your GE-compatible panel is rated for 50A, 120V, 1-pole operation. For optimal performance, install according to GE guidelines and your panel manufacturer’s instructions, keeping the bus connection clean, secure, and free of corrosion or debris.

Whether you're performing a panel upgrade, conducting a routine maintenance replacement, or provisioning a dedicated 50A branch circuit, the GE THQB1150 delivers dependable protection with straightforward installation and a design that stands up to the demands of residential, commercial, and light industrial use.
