General Electric | THHQB1150 | Circuit Breaker | 50A | 1-Pole | 240V | Bolt-On

Meet the General Electric THHQB1150 circuit breaker—a robust 50 A, 1-Pole, 240 V bolt-on unit designed for dependable protection in service panels. Built for maintenance, retrofit, and replacement projects, this GE component is the precise fit you need when the panel calls for a THHQB1150 reference.

Key specifications

• Amperage: 50 A
• Poles: 1-Pole
• Voltage: 240 V
• Mounting: Bolt-On
• Part reference: THHQB1150
• Ideal uses: Maintenance, retrofit, and replacement in compatible GE panels

Why this breaker matters

The THHQB1150 is more than a rating on a label. Its bolt-on design delivers a secure, stable connection that stands up to panel vibration and field handling. With a 50 A rating at 240 V, it protects higher-demand circuits while simplifying panel layouts for contractors and DIY enthusiasts working within GE ecosystems. This specific 1-Pole configuration streamlines installation where a single, high-current branch is appropriate, helping you keep electrical systems organized and compliant.

Who should consider it

Ideal for electricians, facility managers, and homeowners performing panel upgrades, service upgrades, or component replacements in GE-compatible panels. If your project requires a reliable 50 A, 1-Pole, 240 V bolt-on breaker, the THHQB1150 is engineered to meet those exact specifications. Always verify that your panel’s line, load, bus configuration, and labeling align with this part number.

Compatibility and installation tips

• Reference your fit: Use THHQB1150 as the primary compatibility reference to ensure the breaker matches your GE panel.
• Before you begin: Power down the main disconnect and follow local electrical codes. Use proper PPE and testing procedures.
• Installation guidance: Install the bolt-on breaker into a compatible bus and secure mounting hardware per GE’s instructions. Adhere to any torque specs or sequencing provided by your panel’s documentation.
• Post-install verification: After mounting, confirm the circuit protects the intended load and that the breaker trips correctly under fault conditions when tested by a qualified professional.

Practical use cases

Consider the THHQB1150 for scenarios such as replacing a failed or outdated GE breaker, upgrading a circuit to accommodate higher loads on a 240 V branch, or executing a retrofit where a 50 A, 1-Pole, 240 V bolt-on solution aligns with panel requirements. This unit fits seamlessly into GE-based electrical ecosystems, helping you maintain code-compliant protection without unnecessary parts juggling.
