ABB KT7XS6 is a T7-X1 shunt trip release accessory for ABB Tmax Series circuit breakers, designated as a shunt opening release (YO) with a 110–120 V control voltage. The coil is rated at 110–120 V, and ABB catalogs note that similar YO releases are available for 110–120 V AC/DC variants, enabling remote tripping in protection schemes. Designed for use with Tmax Series T7 frame breakers, KT7XS6 provides a direct, energize-to-trip function by applying the control voltage to the release.
