Why Choose the ABB 1SDA054888R1 UVR-C Undervoltage Release?
The ABB 1SDA054888R1 is a cabled UVR-C undervoltage release designed for use with compatible ABB SACE Tmax T4, T5 and T6 moulded case circuit breakers. As part of the ABB SACE Tmax circuit breaker accessory range, it provides automatic circuit breaker opening when the control supply voltage falls below the required operating level.
The UVR-C supports electrical protection and control by ensuring that a compatible circuit breaker responds to an unacceptable reduction or loss of its control supply. This functionality is particularly useful in industrial power distribution, machinery and automation systems where equipment must be disconnected following an undervoltage condition.
With a rated control voltage of 48 V AC/DC, the 1SDA054888R1 is suitable for both AC and DC control circuits. Its cabled configuration is specifically designed for ABB SACE Tmax T4, T5 and T6 circuit breakers, providing straightforward integration into compatible switchboards, distribution panels and industrial control systems.

Reliable Undervoltage Protection for Circuit Breakers
An undervoltage release operates in conjunction with a circuit breaker to provide controlled disconnection when its control supply falls below the level necessary for normal operation. This allows electrical systems to respond automatically to significant voltage reductions or complete loss of control voltage without relying on manual breaker operation.
The ABB UVR-C range is engineered specifically for compatible SACE Tmax circuit breakers. The 1SDA054888R1 is the 48 V AC/DC cabled version for Tmax T4, T5 and T6, making it suitable for industrial installations that use 48 V control circuits and require dependable undervoltage-operated breaker control.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Machinery requiring undervoltage-operated disconnection.
- Industrial automation and control panels.
- Motor control and protection systems.
- Power distribution and electrical protection systems.
- ABB Tmax T4, T5 and T6 installations using 48 V AC/DC control circuits.
