ABB / General Electric THQMV200 Molded Case Circuit Breaker

This breaker is designed specifically for use as a main breaker in GE PowerMark Gold load centers rated between 150A and 225A.

The THQMV200E is the current drop-in replacement for the legacy THQMV200 and THQMV200D models. It serves as an exact substitute for these discontinued main breakers.

Following ABB's acquisition of GE Industrial Solutions, these breakers are manufactured under the ABB name. The product remains identical in form, fit, and function regardless of whether it carries the GE or ABB label.

The THQMV200 is engineered to function as a main circuit breaker, typically used in top-feed configurations to control power and provide overcurrent protection for the entire load center.

It uses a plug-in connection that engages with the load center interior. As a main breaker, it must also be secured to the panel base with mounting screws to ensure a rigid, safe connection.

Depending on the specific panel configuration and local NEC requirements, a service barrier and flapper may be required over the main terminals to maintain electrical isolation and protect personnel from accidental contact with live components.

It utilizes fixed thermal-magnetic trip technology with long-time and instantaneous (LI) functions. The thermal element responds to prolonged overloads, while the magnetic element trips instantly during short circuits.

Yes, it provides a maximum interrupting rating of 22kA at 240V, making it suitable for residential and light commercial services that require higher fault-clearing capabilities than standard 10kAIC breakers.
