GE THHQB2150 - 50 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

GE THHQB2150 delivers dependable branch circuit protection in a compact, rugged package. This 50A, 240V, 2-pole bolt-on molded case circuit breaker is built for panelboards and load centers, offering a secure connection and reliable performance across residential, commercial, and light industrial applications.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight through real-world panel vibrations and door closures, reducing the risk of loose connections over time.
• Thermal-magnetic trip unit combines predictable overload protection (thermal) with instantaneous short-circuit protection (magnetic), delivering stable, repeatable tripping behavior you can trust under varying loads.
• OEM-compatible design ensures seamless fit and electrical coordination with matching GE OEM load centers and panelboards, simplifying replacement and upgrades.
• Versatile, all-in-one protection handles branch-circuit overcurrent and short-circuit events, helping to safeguard wiring, devices, and downstream equipment without nuisance trips.
• Broad applicability ideal for residential circuits, commercial subpanels, and light-industrial feeders where reliable 2-pole protection is required.

Why this breaker stands out

Beyond simply meeting a specification, the THHQB2150 is engineered to withstand real-world panel conditions. The bolt-on mounting creates a solid mechanical bond that resists loosening from vibrations, cycling, or thermal expansion—an important consideration for busy service panels and equipment rooms. The thermal-magnetic trip unit provides predictable, fast clearing of faults, reducing the energy delivered to faulted circuits and protecting wires and devices from damage.

Practical use cases

• Upgrading residential service panels that require a reliable 50A, 240V protection on a dedicated circuit (e.g., electric water heater, multi-room subfeeds).
• Feeding subpanels in light commercial spaces where panel reliability and robust mounting are priorities.
• Replacing aging breakers in panelboards to ensure compatibility with GE OEM panels and maintain system coordination.

Installation and care tips

• Install only in matching GE OEM load centers or panelboards to preserve electrical coordination and warranty where applicable.
• Ensure the mounting screws and bus connections are clean, dry, and properly seated to maximize the benefits of the bolt-on design.
• Use as part of a thoughtfully designed protection scheme: pair with appropriately rated conductors and overcurrent protection downstream to optimize safety and reliability.

Choose the GE THHQB2150 for a durable, dependable two-pole solution that tackles overcurrent and short-circuit protection with a mounting approach designed for longevity. Ideal for electricians, facilities managers, and discerning homeowners upgrading panels, this breaker delivers clear, repeatable protection where it matters most.
