Why Choose the ABB 1SDA038304R1 Shunt Closing Release?
The ABB 1SDA038304R1 is a dependable 380–400 V AC shunt closing release designed for remote electrical closing of compatible ABB SACE Emax circuit breakers. Identified as the YC closing release, this genuine ABB electrical accessory enables the breaker closing mechanism to be operated from an external control circuit.
Designed for the ABB SACE E1–E6 Emax range, the closing release provides an important interface between the circuit breaker and remote control, automation and switching systems. When the appropriate control voltage is applied and the breaker is ready to close, the release actuates the stored-energy closing mechanism to close the main contacts.
With a rated control voltage of 380–400 V AC, the 1SDA038304R1 is suited to industrial switchboards and power-distribution installations using high-voltage AC control circuits. Its ABB-specific design helps ensure correct integration with compatible Emax breaker mechanisms in automated and remotely controlled electrical systems.

Reliable Remote Closing for SACE Emax Circuit Breakers
A shunt closing release provides an electrical means of initiating circuit-breaker closing from a remote location. When its specified control voltage is applied, the closing release operates the breaker’s closing mechanism, provided the breaker is in the correct operating condition and its stored-energy mechanism is ready for closing.
The ABB 1SDA038304R1 is particularly useful in switchboards where circuit breakers form part of an automated power-management system. It allows compatible Emax breakers to respond to remote closing commands from control panels, PLC systems, transfer schemes and other supervisory equipment.
Typical Applications
- Remote closing of ABB SACE Emax circuit breakers.
- Industrial low-voltage switchboards.
- Automated power-distribution systems.
- Electrical control and supervisory systems.
- Automatic transfer and switching schemes.
- Motorised and remotely operated switchgear.
- Industrial power-management installations.
