Reliable Remote Circuit Breaker Opening
A shunt opening release provides an electrical means of opening a circuit breaker from a remote location. When the specified control voltage is applied to the YO release, the accessory actuates the breaker opening mechanism, allowing switching and protection functions to be incorporated into external control and automation circuits.
The ABB 1SDA073668R1 is designed specifically for compatible ABB circuit breakers, helping ensure correct mechanical and electrical integration. Its 24 V AC/DC operating capability makes it particularly suitable for low-voltage control systems used in switchboards, industrial automation and building power distribution.
Typical Applications
- Remote opening of ABB Emax 2 air circuit breakers.
- Electrical distribution switchboards and control panels.
- Industrial automation and remote switching systems.
- Emergency breaker opening circuits.
- Building and infrastructure power distribution.
- Compatible ABB SACE Tmax XT7 and XT7M circuit-breaker installations.
