General Electric THQB32090ST1NN Circuit Breaker

The General Electric THQB32090ST1NN is a 90A, 240V, three-pole circuit breaker designed to protect electrical circuits from overcurrent by interrupting fault currents. This GE device belongs to the THQB family and is intended for use in 3P, 240V installations, delivering reliable interruption at the 90-amp rating to safeguard wiring, motors, and connected equipment. The three-pole design ensures all three hot conductors are simultaneously opened during a fault, which helps maintain phase balance and reduces damage to downstream devices in 3-phase systems. The model THQB32090ST1NN uniquely identifies this exact current rating and voltage within GE's line, supporting precise selection for protective schemes in appropriate electrical distributions and aligning with GE's standard cataloging for replacement parts in service panels and industrial controls.
