GE THQB2150ST1 - 50 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The GE THQB2150ST1 is a rugged 2-pole, 50A, 240V bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built for environments where vibration and real-world load swings are a factor, this unit stays securely connected while delivering precise protection when it’s needed most.

Why this breaker stands out

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection that stays tight in demanding settings—minimizing connection drift and maintaining consistent performance over time.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding predictably to overloads and short circuits, helping to limit equipment damage and electrical outages.
• 2-pole, 50A, 240V configuration is ideal for protecting heavier feeders and demanding branch circuits, including HVAC feeders, large appliances, and subpanel routes.
• OEM compatibility designed for seamless integration with GE OEM load centers and panelboards, ensuring reliable fit and consistent trip characteristics with matching components.
• Versatile application suited for residential, commercial, and light industrial installations, from home subpanels to small business panels and distribution setups.

How it helps you in real-world scenarios

• In a home service panel, use the THQB2150ST1 to protect a high‑demand circuit such as a central air conditioner or electric water heater, providing fast isolation if a fault occurs while keeping other circuits online.
• In a small commercial or workshop panel, this 50A breaker serves as a dependable main-branch protection point for large lighting and equipment circuits, reducing the risk of nuisance trips and enabling safer maintenance.
• In light industrial applications, it secures feeder lines to subpanels or specialized equipment, with the bolt-on design offering a more secure connection in environments with vibration or frequent equipment cycling.

What makes it a smart choice

• Designed to pair with GE’s line of load centers and panelboards, the THQB2150ST1 helps ensure consistent trip curves and predictable performance across the electrical system.
• The combination of a robust physical installation (bolt-on) and a responsive protection mechanism (thermal-magnetic) reduces downtime and simplifies troubleshooting when circuits are stressed.
• Choosing the right ampacity and voltage rating for your circuit minimizes the risk of nuisance trips while still providing strong protection against overloads and short circuits.

Installation notes

Install in compatible GE panelboards or load centers, following standard electrical safety practices and local codes. Ensure power is off before service, and follow the manufacturer’s installation guidance for bolt-on breakers to achieve the intended secure connection and protective performance.
