Why Choose the ABB 1SDA038293R1 Shunt Opening Release?
The ABB 1SDA038293R1 is a dependable shunt opening release (YO) designed for remote electrical opening of compatible ABB circuit breakers. As part of the ABB SACE Emax accessory range, it enables a circuit breaker to be tripped by applying an external control voltage, providing effective integration with switchboard control, automation and emergency shutdown systems.
This release is rated for a 240–250 V AC/DC control supply under IEC specifications and is suitable for ABB E1, E2, E3, E4, E6 and T8 circuit breakers. Its AC/DC capability provides flexibility when integrating the accessory into industrial control circuits and low-voltage power distribution systems.
The opening and closing releases used with the Emax platform share the same construction, with their function determined by the mounting position within the circuit breaker. The 1SDA038293R1 is specified as a shunt opening release and provides electrically initiated breaker opening for applications requiring remote control or automatic isolation.

Reliable Remote Circuit Breaker Tripping
A shunt opening release provides an electrical means of opening a circuit breaker without requiring direct manual operation. When the specified control voltage is applied to the release, the mechanism acts on the circuit breaker operating system to open the main contacts, making it suitable for remote control and automated isolation functions.
Within ABB SACE Emax circuit breakers, the shunt opening release and shunt closing release use the same basic construction, with their operating function determined by their mounting position. This modular arrangement supports flexible circuit breaker configuration while simplifying integration into industrial switchboards and control systems.
Typical Applications
- Low-voltage switchboards and power distribution panels.
- Remote circuit breaker tripping systems.
- Emergency shutdown and electrical isolation systems.
- Industrial automation and process control installations.
- Building power distribution systems.
- ABB SACE Emax air circuit breaker installations.
- Compatible ABB SACE Tmax T8 circuit breaker installations.
