Why Choose the ABB S2C-A1U Shunt Opening Release?
The ABB S2C-A1U is a compact shunt opening release (SOR) designed to provide remote electrical tripping of compatible ABB circuit protection devices. Part of ABB's accessory range for UL 489 and UL 1077 miniature circuit breakers, it enables a connected protective device to be opened remotely when the release receives the appropriate control voltage.
Operating across a broad 12–60 V AC/DC control-voltage range, the S2C-A1U can be integrated into low-voltage control, automation and emergency switching circuits. Applying the specified voltage to the release coil actuates the accessory and trips the associated compatible circuit breaker, allowing disconnection to be initiated from a remote control point.
The S2C-A1U is particularly useful in industrial machinery, control panels and building electrical systems where circuit disconnection must be initiated by a push-button, relay, safety circuit or automation system. Its modular construction provides a purpose-designed ABB solution for adding remote trip functionality to compatible protective devices.

Remote Circuit Breaker Tripping for Control and Automation
A shunt opening release enables a circuit breaker to be tripped electrically from a remote location. When the specified control voltage is applied to the ABB S2C-A1U, its release mechanism actuates the associated compatible protective device, providing a convenient means of initiating circuit disconnection without manually operating the breaker.
The 12–60 V AC/DC operating range makes the S2C-A1U suitable for a variety of low-voltage control architectures. This allows remote trip commands to be incorporated into appropriately designed emergency controls, machinery systems, relay logic and building or industrial automation applications.
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.
