General Electric THQB32050ST1 Shunt Trip Circuit Breaker

The General Electric THQB32050ST1 is a 3-pole, 50-amp, 240-volt shunt-trip circuit breaker designed for safety-critical electrical systems where remote shutdown is required, such as industrial control panels, motor control centers, and protection schemes. As a shunt-trip device, it can be energized by an external coil to trip the breaker and disconnect power without manual operation, providing fast, automatic isolation in emergency or automated safety sequences. This GE THQB series unit is suited for 3-phase circuits in industrial control panels, building automation, and equipment safety interlocks, offering protection for 50 A loads while fitting standard GE panel installations. Key specs to verify include its 3-pole construction, 50 A rating, and 240 V operating voltage, with compatibility to GE's THQB family for straightforward replacement in compatible panels. Used in control systems that require remote trip signals, it helps coordinate protection with other protective devices in a safety scheme.
