The GE THQB2170-STI Shunt Trip Accessory is a remote-trip device designed for GE THQB circuit breakers. It is rated for 70 A at 240 V and configured as a two-pole (2P) shunt trip with a 120 V control coil. When energized with the 120 V control signal, it triggers the breaker to disconnect power quickly for emergency shutdowns or protective interlocks. This accessory is used in industrial and commercial electrical systems that employ GE THQB-series breakers to enable fast, remote disconnection.
