ABB / General Electric TQD32150ST1 – 150A 3 Pole Molded Case Circuit Breaker Fan Favorite

Built for industrial systems, the GE TQD32150ST1 is a 3-pole, 150A molded case circuit breaker delivering reliable thermal-magnetic protection with long-time and instantaneous (LI) trip functions. This unit-mount breaker installs into GE A-Series and Spectra panelboards. For modern replacements, the ABB XT3 frame serves as the substitute, requiring a retrofit kit and shunt trip accessory. A factory-installed 120VAC shunt trip enables remote shutdown. It provides a 10kAIC rating at 240VAC.
