Why Choose the ABB YU-C XT6 W 1SDA104966R1 Undervoltage Release?
The ABB 1SDA104966R1 is a wired undervoltage release (YU-C) designed for use with ABB SACE Tmax XT6 withdrawable circuit breakers. Part of the ABB Tmax XT electrical accessory range, it provides automatic circuit-breaker tripping when the control supply voltage falls below the required operating level.
Designed specifically for the XT6 withdrawable circuit-breaker configuration, the YU-C undervoltage release integrates with the breaker operating mechanism to provide dependable voltage supervision and automatic opening. This makes it suitable for industrial switchboards, power distribution systems and machinery where equipment must be disconnected following a significant reduction or loss of control voltage.
The 1SDA104966R1 operates from a 380–440 V AC control supply and is suitable for both 50 Hz and 60 Hz AC systems. Its wired configuration simplifies integration into compatible XT6 withdrawable circuit-breaker assemblies while maintaining the performance and compatibility of a genuine ABB accessory.
