Why Choose the ABB 1SDA050166R1 Additional Shunt Opening Release?
The ABB 1SDA050166R1 is an additional YO2 shunt opening release designed for remote electrical opening of compatible ABB circuit breakers. Part of the ABB New Emax accessory range, it provides a second electrically operated opening function for E1/6 and T8 circuit-breaker applications.
This shunt opening release actuates the circuit breaker's opening mechanism when the appropriate control voltage is applied, allowing the breaker to be tripped remotely by protection, control, interlocking or automation equipment. It is suitable for industrial switchboards and power distribution systems where dependable remote breaker opening is required.
With a rated control supply of 440 V AC, the 1SDA050166R1 is intended for high-voltage AC control circuits. Its additional YO2 configuration provides a dedicated second opening command for compatible ABB Emax E1 through E6 and Tmax T8 circuit breakers.

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, the release actuates the breaker opening mechanism, enabling rapid disconnection through an external protection, control, interlocking or automation circuit.
As the additional YO2 release, the ABB 1SDA050166R1 provides a second electrically controlled opening function for compatible breakers. This makes it suitable for installations requiring an additional trip command from protection relays, emergency shutdown 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 Emax E1-E6 and Tmax T8 circuit-breaker installations.
