THQB32030ST1 - 30Amp Circuit Breaker Description
THQB32030ST1 - 30 Amp Circuit Breaker
The THQB32030ST1 is a 30-amp, 3-pole bolt-on circuit breaker equipped with a 120VAC shunt trip for your applications that require remote tripping capability. As part of the THQB Q-Line series, it is commonly used in commercial and industrial electrical systems where three-phase circuit protection and controlled shutdown functions are needed.
This breaker provides overcurrent protection while also allowing the circuit to be opened remotely through an external control signal. That makes it a practical choice for emergency stop systems, safety interlocks, building automation controls, and other installations where power may need to be disconnected without manually operating the breaker.
Rated 10kA at 240VAC, the THQB32030ST1 is suitable for a variety of distribution and equipment protection applications. The bolt-on mounting configuration provides a secure connection within compatible panelboards, and its HACR rating allows use in heating, ventilation, air conditioning, and refrigeration systems.
