Why Choose the ABB YO E1.2..E6.2 110-120 VAC/DC Shunt Opening Release?
The ABB YO E1.2..E6.2 110-120 VAC/DC, order code 1SDA073672R1, is an electrical shunt opening release designed for remote opening of compatible ABB SACE Emax 2 air circuit breakers. Operating from a 110–120 V AC/DC control supply, the YO release enables the associated circuit breaker to be electrically tripped from a remote control circuit.
ABB identifies YO as the first and second opening release within the Emax 2 electrical accessory range. When the appropriate control voltage is applied, the release actuates the breaker opening mechanism, making it suitable for remote trip commands, emergency-opening circuits and automated switchboard control schemes.
The 1SDA073672R1 is suitable for ABB SACE Emax 2 E1.2, E2.2, E4.2 and E6.2 circuit breakers and is also listed for compatible XT7 and XT7M products. Its dual AC/DC voltage capability simplifies control-system integration where a 110–120 V operating supply is available.

Remote Opening for ABB SACE Emax 2 Circuit Breakers
A shunt opening release allows a circuit breaker to be opened electrically without requiring manual operation at the breaker itself. The ABB YO 1SDA073672R1 performs this function using a 110–120 V AC/DC control signal, allowing compatible Emax 2 breakers to respond to remote trip commands from control panels, automation equipment or other suitable control circuits.
Because the YO accessory is designed specifically for the ABB breaker operating mechanism, it provides a purpose-engineered solution for adding remote opening capability to compatible Emax 2 installations. Its compatibility across the E1.2 through E6.2 frame range also helps standardise control accessories across switchboards containing multiple Emax 2 breaker sizes.
Typical Applications
- Remote opening of ABB SACE Emax 2 air circuit breakers.
- Industrial low-voltage distribution switchboards.
- Emergency and remote breaker-opening circuits.
- Building and process automation systems.
- Generator and power-management switchboards.
- Automated electrical distribution and breaker-control systems.
