Why Choose the ABB YC E1.2..E6.2 240-250 VAC/DC Shunt Closing Release?
The ABB YC E1.2..E6.2 240-250 VAC/DC, order code 1SDA073688R1, is a shunt closing release designed for electrical closing of compatible ABB SACE Emax 2 air circuit breakers. Operating from a 240–250 V AC/DC control supply, the YC accessory enables a compatible breaker to be electrically closed from a suitable local or remote control circuit.
ABB identifies YC as the first and second closing coil within the Emax 2 electrical accessory range. When the appropriate control signal is applied and the breaker mechanism is ready for closing, the YC release actuates the closing mechanism, supporting remote operation, power-management functions and automated switchboard control.
The 1SDA073688R1 is suitable for ABB SACE Emax 2 E1.2, E2.2, E4.2 and E6.2 circuit breakers and is also compatible with applicable ABB SACE Tmax XT7/XT7M products. Its AC/DC operating capability provides flexibility for installations using 240–250 V control systems.

Remote Closing for ABB SACE Emax 2 Circuit Breakers
A shunt closing release allows a compatible circuit breaker to be closed electrically rather than relying solely on local manual operation. The ABB YC 1SDA073688R1 performs this function from a 240–250 V AC/DC control system, enabling breaker closing to be initiated from a suitable control panel, automation system, power-management system or remote command circuit.
Because the YC accessory is engineered for compatible ABB circuit breaker mechanisms, it provides a purpose-designed solution for adding electrical closing capability to Emax 2 installations. Compatibility across the E1.2 through E6.2 frame range also helps standardise control accessories in switchboards containing multiple ABB Emax 2 breaker sizes.
Typical Applications
- Remote electrical closing of ABB SACE Emax 2 air circuit breakers.
- Industrial low-voltage distribution switchboards.
- Automated circuit breaker control systems.
- Building and process automation installations.
- Generator and power-management switchboards.
- Remote switching and electrical distribution control systems.
