Why Choose the ABB YC E1.2..E6.2 120-127 VAC/DC Shunt Closing Release?
The ABB YC E1.2..E6.2 120-127 VAC/DC, order code 1SDA073686R1, is a shunt closing release designed for electrical closing of compatible ABB SACE Emax 2 air circuit breakers. Operating from a 120–127 V AC/DC control supply, the YC accessory enables a compatible breaker to be closed electrically 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 and integration into automated switchboard control schemes.
The 1SDA073686R1 is suitable for ABB SACE Emax 2 E1.2, E2.2, E4.2 and E6.2 circuit breakers and is also listed for compatible ABB SACE Tmax XT7 and XT7M products. Its AC/DC operating capability makes it a flexible solution for installations using 120–127 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 solely through local manual operation. The ABB YC 1SDA073686R1 performs this function using a 120–127 V AC/DC control supply, enabling the breaker closing mechanism to be operated from a suitable control panel, automation system or remote command circuit.
Because the YC accessory is engineered specifically for compatible ABB circuit breaker mechanisms, it provides a purpose-designed method of adding electrical closing capability to Emax 2 installations. Compatibility across the E1.2 through E6.2 frame range also helps standardise control accessories within 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.
