Why Choose the ABB 1SDA050161R1 Emax YO2 Additional Shunt Opening Release?
The ABB 1SDA050161R1 is an additional shunt opening release (YO2) designed for compatible ABB SACE Emax E1–E6 and SACE Tmax T8 circuit breakers. Identified by ABB as SHUNT OPEN.RELEAS ADDIT.110/120V E1/6-T8, it provides an additional electrically operated method of opening the circuit breaker from a remote control or protection circuit.
The release operates from a rated control voltage of 110–120 V AC/DC. When the appropriate control voltage is applied, the YO2 release actuates the circuit breaker opening mechanism, enabling remote trip commands from switchboard controls, protection equipment, automation systems and emergency shutdown circuits.
As part of the ABB SACE Emax accessory range, the 1SDA050161R1 is suitable for E1, E2, E3, E4, E6 and T8 circuit breakers. Its additional-release configuration provides a supplementary trip channel where installations require a second electrically initiated opening function alongside the primary breaker controls.
Key Advantages
- Provides additional remote electrical opening of compatible ABB circuit breakers.
- Operates across a 110–120 V AC/DC control voltage range.
- Designed as the YO2 additional / second shunt opening release.
- Suitable for compatible ABB SACE Emax E1–E6 and Tmax T8 circuit breakers.
- Supports automation, protection, remote trip and emergency shutdown functions.
- Genuine ABB accessory engineered for dependable circuit breaker integration.

110–120 V AC/DC Additional Remote Opening for ABB Switchgear
Remote circuit breaker opening allows protection and control systems to disconnect a circuit without direct manual operation at the breaker. The ABB 1SDA050161R1 converts a compatible 110–120 V AC/DC electrical command into mechanical actuation of the circuit breaker opening mechanism.
Because the 1SDA050161R1 is the YO2 additional shunt opening release, it can provide a supplementary electrically initiated trip path in compatible Emax and Tmax T8 installations. This makes it useful where separate remote control, protection, process interlocking or emergency shutdown functions require an additional opening command.
Typical Applications
- ABB SACE Emax E1–E6 air circuit breaker installations.
- Compatible ABB SACE Tmax T8 circuit breaker installations.
- Additional or second remote trip circuits.
- 110–120 V AC/DC switchboard control systems.
- PLC and industrial automation systems.
- Protection, interlocking and emergency shutdown circuits.
- Industrial and commercial low-voltage power distribution switchboards.
