General Electric THQMV150 Main Circuit Breaker

The General Electric THQMV150 is a highly specialized 2-pole, 150-ampere, 240-volt main circuit breaker engineered for complex high-capacity electrical distribution applications requiring precise interruption capabilities. Designed specifically for use within THQL series load centers manufactured by General Electric, this unit provides essential fault protection by monitoring continuous current flow through two distinct hot legs operating at 240 volts simultaneously.

Its rugged physical construction facilitates direct replacement of existing standard main breakers, allowing facility managers to upgrade service entrance equipment ratings significantly during routine renovation projects without extensive rewiring of the internal bus bar assembly. By integrating advanced thermal magnetic trip technology, the device reliably interrupts electrical flow before excessive heat damages connected wiring insulation or creates fire hazards in demanding commercial and light industrial building management systems.
