Why Choose the ABB 1SDA050164R1 Additional Shunt Opening Release?
The ABB 1SDA050164R1 is a genuine ABB YO2 additional shunt opening release designed to provide remote electrical opening of compatible ABB SACE Emax and Tmax T circuit breakers. Rated for a 240–250 V AC/DC control supply, it provides a second electrically operated opening function for industrial power distribution and circuit-breaker control systems.
As an ABB circuit-breaker accessory, the 1SDA050164R1 actuates the breaker opening mechanism when the specified control voltage is applied. This enables the breaker to be tripped remotely by protection equipment, emergency shutdown controls, interlocking circuits or industrial automation systems without requiring manual operation at the breaker.
The 1SDA050164R1 is identified as the YO2 second shunt opening release and is suitable for ABB E1, E2, E3, E4, E6 and T8 circuit breakers. Its AC/DC control-voltage capability makes it a versatile solution for switchboards and electrical distribution installations requiring an additional independent opening command.

Reliable Remote Circuit-Breaker Opening
A shunt opening release allows a circuit breaker to be opened electrically from a remote control point. When the specified control voltage is applied to the release, it actuates the breaker opening mechanism, enabling rapid disconnection through an external protection, control or automation circuit.
As the additional YO2 release, the ABB 1SDA050164R1 provides a second electrically controlled opening function for compatible circuit breakers. This makes it particularly useful in installations requiring independent trip commands from protection relays, emergency systems, process controls or switchboard interlocking arrangements.
Typical Applications
- Low-voltage power distribution switchboards.
- Remote circuit-breaker trip circuits.
- Industrial electrical control systems.
- Emergency shutdown and opening circuits.
- Protection relay and interlocking schemes.
- Automated power distribution systems.
- ABB SACE Emax and Tmax T circuit-breaker installations.
