Why Choose the ABB S800-UVR250 Undervoltage Release?
The ABB S800-UVR250 is an undervoltage release (UVR) accessory designed for compatible ABB S800 high-performance circuit breakers. It adds voltage-dependent tripping functionality to the associated breaker, allowing the protective device to open when the control supply falls below the undervoltage release's operating threshold.
Designed for a control supply range of 220–250 V AC/DC, the S800-UVR250 is suitable for industrial control, machinery and electrical distribution applications where a significant reduction or loss of control voltage must initiate circuit-breaker tripping. This makes it useful in control and interlocking schemes where continued operation following loss of the required control supply is undesirable.
As part of the coordinated ABB S800 accessory system, the S800-UVR250 provides a dedicated solution for adding undervoltage-dependent operation to compatible circuit breakers. ABB order code 2CCS800900R0271 uniquely identifies this 220–250 V AC/DC undervoltage release.

Reliable Undervoltage-Dependent Circuit Breaker Tripping
An undervoltage release responds to the condition of its control supply and acts on the associated circuit-breaker mechanism when the voltage falls below the required operating level. This enables the breaker to open following an unacceptable reduction or loss of control voltage, providing a useful function in machinery, automation and electrical distribution systems.
The ABB S800-UVR250 is specifically designed for 220–250 V AC/DC control circuits and integrates with compatible S800 circuit breakers. The associated breaker continues to provide its normal overload and short-circuit protection, while the S800-UVR250 adds the required undervoltage-dependent tripping functionality.
Typical Applications
- Industrial machinery control systems.
- Electrical distribution panels and switchboards.
- Automation and process-control equipment.
- Control circuits requiring undervoltage-dependent tripping.
- Electrical interlocking systems.
- OEM machine and equipment panels.
- Compatible ABB S800 circuit-breaker installations.

Frequently Asked Questions
What is the ABB S800-UVR250 used for?
The S800-UVR250 is an undervoltage release used with compatible ABB S800 circuit breakers to provide voltage-dependent tripping when the control supply falls below the required operating level.
What control voltage does the ABB S800-UVR250 use?
The S800-UVR250 is designed for a control voltage range of 220–250 V AC/DC.
What does an undervoltage release do?
An undervoltage release acts on the associated circuit breaker when its control voltage falls sufficiently below the required operating level, allowing the breaker to trip as part of a control, interlocking or equipment-protection scheme.
Is the ABB S800-UVR250 itself a circuit breaker?
No. The S800-UVR250 is an electrical circuit-breaker accessory. Overload and short-circuit protection remains the function of the compatible ABB S800 circuit breaker.
What is the ABB order code for the S800-UVR250?
The ABB order code for the S800-UVR250 undervoltage release is 2CCS800900R0271.
