Why Choose the ABB YC E1.2..E6.2 24 Vac/dc Shunt Closing Release?
The ABB YC E1.2..E6.2 24 Vac/dc, order code 1SDA073681R1, is a 24 V AC/DC shunt closing release designed for electrical closing of compatible ABB low-voltage circuit breakers. Part of the accessory range for the ABB SACE Emax 2 family, this closing coil is suitable for E1.2, E2.2, E4.2 and E6.2 circuit breakers and provides a reliable means of initiating breaker closing from an electrical control circuit.
The YC closing release operates the circuit breaker's closing mechanism when the appropriate control voltage is applied, provided the breaker is ready to close. This allows circuit-breaker closing to be incorporated into remote control panels, automation systems and electrical distribution control schemes, reducing the need for direct manual operation at the switchgear.
With a rated control supply of 24 V AC/DC, the 1SDA073681R1 can be used with both AC and DC control circuits. It is also suitable for compatible ABB SACE Tmax XT7 and XT7M circuit breakers, providing a versatile ABB-engineered closing accessory for modern low-voltage switchgear installations.

Reliable Electrical Circuit Breaker Closing
A shunt closing release provides an electrical means of operating a circuit breaker's closing mechanism. When the specified control voltage is applied and the breaker mechanism is ready for operation, the YC release initiates closing, allowing circuit-breaker operation to be controlled from external switches, relays, automation equipment or supervisory systems.
The ABB 1SDA073681R1 is designed specifically for compatible ABB circuit breakers and operates from a 24 V AC/DC supply. This makes it particularly suitable for low-voltage control circuits in switchboards, industrial automation systems, power distribution installations and remotely operated electrical equipment.
Typical Applications
- Remote closing of ABB SACE Emax 2 air circuit breakers.
- Low-voltage power distribution switchboards.
- Industrial automation and remote switching systems.
- Automatic power distribution control schemes.
- Commercial and infrastructure electrical installations.
- Compatible ABB SACE Tmax XT7 and XT7M circuit-breaker installations.
