Why Choose the ABB S3CUA230 Undervoltage Release?
The ABB S3CUA230, type designation S3C-UA 230, is an undervoltage release (UVR) designed for compatible ABB modular protection equipment. Supplied under ABB order code 2CDS200985R0045, it forms part of ABB's MCB accessory range and provides voltage-dependent tripping functionality for suitable protection assemblies.
Designed for a 230 V AC/DC control supply, the S3C-UA 230 monitors the presence of its operating voltage and works with the associated compatible protective device to provide undervoltage-release functionality. This makes it useful where automatic opening is required in response to loss or significant reduction of the control supply.
The undervoltage-release principle also helps prevent unintended maintained operation when the required control voltage is unavailable. As a purpose-designed ABB accessory, the S3CUA230 provides a coordinated solution for integrating voltage-dependent protective switching into distribution boards, machine control systems and OEM electrical equipment.
Key Advantages
- Provides undervoltage-release functionality for compatible ABB modular protection equipment.

Reliable Undervoltage Release for Modular Protection Systems
An undervoltage release is used where the operating state of a compatible protective device needs to depend on the presence of a specified control voltage. If that voltage falls sufficiently or is removed, the release operates the associated switching mechanism, helping disconnect the protected circuit rather than allowing equipment to remain energised under an unsuitable supply condition.
The ABB S3C-UA 230 provides this functionality with a 230 V AC/DC rating. It is therefore suited to compatible electrical installations requiring an ABB modular accessory for voltage-dependent tripping in industrial control panels, distribution equipment, machinery and other professionally engineered electrical systems.
Typical Applications
- Undervoltage release of compatible ABB modular protection devices.
- Voltage-dependent electrical protection circuits.
- Industrial machine control systems.
- Commercial and industrial distribution boards.
- Automation and electrical control panels.
- Switchgear and modular protection assemblies.
- OEM electrical equipment requiring undervoltage-release functionality.
