Why Choose the ABB 1SDA038294R1 Shunt Opening Release?
The ABB 1SDA038294R1 is a reliable 380–400 V AC/DC shunt opening release designed for remote electrical opening of compatible ABB circuit breakers. Part of the ABB Accessories for Emax range, it provides an electrically operated method of tripping the breaker from an external control, protection or emergency shutdown circuit.
This shunt opening release is designed for use with compatible ABB SACE Emax and SACE Tmax T circuit breakers. When the rated control voltage is applied, the release actuates the circuit-breaker opening mechanism, enabling remote disconnection without manual operation of the breaker.
With a rated control supply voltage of 380–400 V AC/DC, the 1SDA038294R1 is suitable for higher-voltage industrial control circuits. It is compatible with ABB E1, E2, E3, E4, E6 and T8 circuit breakers, making it suitable for switchboards, distribution systems and industrial power-control installations.

Reliable Remote Opening for Circuit Breakers
A shunt opening release provides an electrical means of opening a circuit breaker remotely. Applying the specified control voltage energises the release and actuates the breaker mechanism, allowing external control equipment to initiate circuit interruption when required.
The ABB 1SDA038294R1 is particularly suited to industrial switchboards and automated power-distribution systems where circuit breakers must respond to remote commands, interlocks, protection signals or emergency shutdown circuits. Its compatibility with multiple Emax and Tmax breaker sizes supports flexible integration within ABB low-voltage installations.
Typical Applications
- Remote opening of industrial circuit breakers.
- Low-voltage switchboards and distribution panels.
- Industrial power-distribution systems.
- Emergency shutdown and isolation circuits.
- Automated electrical control systems.
- Protection and electrical interlocking circuits.
- ABB SACE Emax and SACE Tmax T breaker installations.
