Why this THHQB1170 matters

When you’re supplying a heavy 240V circuit, you need dependable protection that trips reliably to prevent wiring damage and reduce fire risk. The THHQB1170 is built to respond precisely to overload or short-circuit conditions on a dedicated 240V feeder, helping to safeguard both the circuit and connected equipment.

Who this is for

• Homeowners upgrading or maintaining GE panel configurations that call for a 1-pole 240V protection device.
• Electrical professionals seeking a genuine GE replacement part for reliable, industry-standard performance.
• Users installing or reconfiguring high-draw 240V loads in residential or light commercial settings.

Use cases and practical applications

• Protecting large 240V circuit feeders to equipment like HVAC components, air handling units, or other 240V appliances.
• Providing targeted safety for dedicated 240V circuits in GE load centers where a 1-pole solution is appropriate.
• Serving as a straightforward replacement part to restore protective function after a trip or upgrade.

How it compares to alternatives

Compared to multi-pole breakers, the THHQB1170 offers focused protection for a single hot conductor on compatible GE panels. This can be advantageous in configurations where a dedicated 240V feeder needs precise overcurrent protection without affecting other circuits. Built by General Electric, it aligns with GE’s design standards and panel compatibility, helping ensure smoother integration and consistent performance.

Installation and safety notes

• Install only in GE panels that support the THHQB1170 1-pole 240 V configuration and follow all local electrical codes.
• Power must be fully off before installation. If you’re not a licensed electrician, consult one to ensure proper sizing, mounting, and torque specifications.
• Verify that a 70 A rating is suitable for the circuit’s load and conductor sizing, and confirm panel labeling before replacement or installation.

For reliable protection of high-draw 240V circuits, the General Electric THHQB1170 70A 1-Pole 240 V Circuit Breaker offers precise, dependable overcurrent protection with a specification that clearly identifies it as part number THHQB1170. Add this genuine GE component to ensure your 240V feeders stay safeguarded and code-compliant.
