Why Choose the ABB YO E1.2..E6.2 380-400 VAC Shunt Opening Release?
The ABB YO E1.2..E6.2 380-400 VAC, order code 1SDA073677R1, is a shunt opening release designed for remote electrical opening of compatible ABB SACE Emax 2 circuit breakers. Operating from a 380–400 V AC control supply, the YO release enables a breaker to be opened electrically when an external command signal is applied.
The accessory is compatible with ABB SACE Emax 2 E1.2 through E6.2 circuit breakers and is also specified for compatible Tmax XT7 and XT7M devices. This broad compatibility makes the release suitable for switchboard designs requiring remote tripping, emergency opening, automation or electrical interlocking functionality.
As an original ABB electrical accessory, the 1SDA073677R1 is designed for integration with the relevant breaker operating mechanism. It is an opening release rather than a closing coil or undervoltage release, providing a dedicated means of initiating circuit-breaker opening from an external electrical control circuit.

Reliable Remote Circuit-Breaker Opening
The ABB YO shunt opening release provides an electrical method of opening a compatible circuit breaker from a remote control point. When the appropriate control command is applied to the release, it acts on the breaker mechanism to initiate opening, allowing the circuit to be disconnected without requiring local manual operation of the breaker.
This functionality is particularly useful in emergency shutdown, remote control, process automation and electrical interlocking systems. Compatibility across Emax 2 frame sizes from E1.2 through E6.2 also helps standardise control solutions across switchboards incorporating multiple ABB air circuit breaker ratings.
Typical Applications
- Remote opening of ABB SACE Emax 2 air circuit breakers.
- Emergency shutdown systems.
- Industrial low-voltage switchboards.
- Automated power distribution systems.
- Electrical interlocking schemes.
- Building management and remote-control systems.
- Generator and transformer distribution switchgear.
- Industrial, commercial and infrastructure power distribution.
