The ABB 1SDA104926R1, also known as the YO XT5-XT6 Shunt Opening Release, is a genuine ABB electrical accessory designed to provide remote opening (shunt trip) of compatible ABB SACE Tmax XT5 and XT6 moulded-case circuit breakers. When an appropriate control voltage is applied, the release instantly trips the breaker, making it ideal for emergency stop circuits, fire protection systems and remote switching applications.
Designed for permanent service, the accessory operates from a wide control voltage range of 110–240 V AC or 110–250 V DC. It integrates directly into compatible XT5 and XT6 circuit breakers without requiring external modifications, maintaining the reliability and performance expected from the ABB Tmax XT platform.
As an original ABB accessory, the YO shunt opening release enables safe remote disconnection of electrical circuits for industrial automation, machine safety, building management systems and emergency isolation functions.
The ABB YO XT5-XT6 shunt opening release enables remote disconnection of electrical circuits whenever an external control signal is applied. It is commonly integrated into emergency shutdown systems, fire alarm interfaces, process automation equipment and access control systems where immediate electrical isolation is required.
By using an original ABB accessory, installers benefit from full compatibility with Tmax XT circuit breakers while maintaining the manufacturer's specified performance and operational reliability.
