Why Choose the ABB S2C-A2U Shunt Opening Release?
The ABB S2C-A2U is a compact shunt opening release (SOR) designed to provide remote electrical tripping of compatible ABB circuit protection devices. Developed for ABB's UL 489 / UL 1077 MCB product environment, it enables an associated protective device to be opened electrically when the appropriate control voltage is applied.
The S2C-A2U supports a broad control-voltage range of 110–415 V AC and up to 250 V DC, providing flexibility for integration into commercial and industrial control systems. When energised by a suitable remote command, the shunt release actuates the compatible circuit breaker mechanism to initiate disconnection.
This remote-trip capability makes the S2C-A2U useful in machinery, automation, building services and electrical distribution applications where circuit opening needs to be initiated by a push-button, relay, control system or other suitable electrical command. Its modular ABB design provides a purpose-engineered accessory for compatible protective devices.

Remote Circuit Breaker Tripping for Control and Automation
A shunt opening release enables a compatible circuit breaker to be opened electrically from a remote control point. When the specified control voltage is applied to the ABB S2C-A2U, the release actuates the associated breaker mechanism, allowing circuit disconnection to be initiated without manual operation at the protective device.
Its broad 110–415 V AC and up to 250 V DC operating range supports integration into a variety of appropriately engineered control architectures. This makes the S2C-A2U suitable for remote switching commands from relays, push-buttons, automation equipment and other compatible control circuits.
Typical Applications
- Remote circuit-breaker tripping.
- Industrial machinery control panels.
- Electrical automation systems.
- Remote shutdown circuits.
- Control circuits using relays or push-buttons.
- Commercial and industrial electrical distribution equipment.
- Compatible ABB UL 489 and UL 1077 circuit protection assemblies.
