General Electric THQMH100CP 100A 2-Pole 240 V Circuit Breaker Potential Transformer

General Electric THQMH100CP is a 100-amp, two-pole, 240-volt circuit breaker designed to guard your electrical distribution system against overloads and short circuits. With part number THQMH100CP, this GE breaker provides robust protection for reliable operation in residential and light commercial panels.

Key specifications

• Current rating: 100 A
• Poles: 2
• Voltage rating: 240 V
• Part number: THQMH100CP

Why this 2-pole 240V breaker matters

Two-pole design means both hot legs are protected together, which is essential for 240V circuits and for equipment that requires simultaneous isolation. This reduces the risk of dangerous line-to-neutral imbalances and ensures the protected circuit trips cohesively when faults occur.

Ideal use cases

• Distributing and protecting 240V appliances and equipment in homes or small businesses (e.g., electric dryers, air compressors, and heat pumps).
• Main or branch protection in GE-compatible panels where a 100A, two-pole device fits the space and rating requirements.
• Systems that rely on coordinated protection for multi-wire branch circuits where both legs must be shut off together for safety.

What makes it unique

Unlike generic breakers, the GE THQMH100CP is a purpose-built component designed to integrate with GE distribution systems and maintain consistent electrical performance across installations. Its form factor and latching mechanism are engineered for dependable seating in standard GE panels, reducing the chance of loose connections that can lead to nuisance trips.

How to install and maintain

Install only in compatible GE panels and follow manufacturer torque specs for the lugs. Ensure the circuit is de-energized before service, use appropriate insulating tools, and verify the breaker seats fully and evenly. Periodically inspect for signs of wear or overheating, and replace if the breaker trips frequently or shows physical damage.

In related protection and metering setups

In systems that involve potential transformers for metering or protective relays, this 2-pole breaker provides the essential protective layer, ensuring safe disconnection of both hot legs during faults and contributing to accurate, reliable protection schemes.

For whom this is designed

Electricians, facilities managers, and DIY enthusiasts who require a reliable 2-pole 240V protection solution with a 100A rating. This part is well-suited for upgrading, replacing, or stocking spare protective devices in GE-based electrical systems.
