General Electric THQB32020ST1U Circuit Breaker

The General Electric THQB32020ST1U is a GE THQB series three-pole circuit breaker rated at 20 amps and 240 volts. Identified by the exact part number THQB32020ST1U, this device is designed to provide overcurrent protection for 3‑phase electrical circuits by interrupting fault currents and helping prevent damage to conductors and connected equipment. The 20A, 240V rating specifies the maximum load the breaker is intended to carry and the voltage level at which it operates, enabling safer operation of three‑phase distribution systems where GE protection devices are specified. As a GE component, it corresponds to a specific configuration within the THQB family, ensuring a precise match for replacement or specification in electrical plans and maintenance records. In applications requiring three‑phase protection with a 20‑amp branch circuit, the THQB32020ST1U delivers a straightforward, standards‑compliant means to isolate faults and safeguard downstream wiring.
