Why Choose the ABB YO E1.2..E6.2 120-127 VAC/DC Shunt Opening Release?
The ABB YO E1.2..E6.2 120-127 VAC/DC, order code 1SDA073673R1, is an electrical shunt opening release designed for remote opening of compatible ABB SACE Emax 2 air circuit breakers. Operating from a 120–127 V AC/DC control supply, the YO release enables the associated circuit breaker to be electrically opened by a remote control signal.
ABB identifies YO as the first and second opening release within the Emax 2 electrical accessory range. When its specified control voltage is applied, the release acts on the breaker opening mechanism, making it suitable for remote trip commands, emergency-opening circuits and automated switchboard control systems.
The 1SDA073673R1 is designed for ABB SACE Emax 2 E1.2, E2.2, E4.2 and E6.2 frame sizes and is also compatible with applicable ABB SACE Tmax XT7 and XT7M products. Its AC/DC capability provides flexibility for installations using 120–127 V control circuits.

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 1SDA073673R1 performs this function from a 120–127 V AC/DC control circuit, enabling compatible breakers to respond to remote trip commands from control panels, automation equipment, safety systems or other suitable control devices.
Because the YO accessory is engineered for compatible ABB breaker mechanisms, it provides a purpose-designed method of adding remote opening capability to Emax 2 installations. Compatibility across the E1.2 through E6.2 frame range also supports standardisation of breaker-control accessories in switchboards containing different Emax 2 frame 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.
