Why Choose the ABB UVD XT5-XT6 220–250 V AC/DC Time Delay Device?
The ABB UVD XT5-XT6 220–250 V AC/DC, order code 1SDA101982R1, is an electronic time delay device for undervoltage releases designed for ABB SACE Tmax XT5 and XT6 circuit breakers. It introduces a controlled delay into compatible undervoltage-release operation, helping prevent unnecessary breaker opening during brief voltage disturbances.
Designed specifically for the ABB SACE Tmax XT5 and XT6 platforms, this UVD accessory operates from a rated voltage of 220–250 V AC/DC. It works with a compatible undervoltage release to delay its response when the monitored control voltage falls below the required operating level.
The UVD is particularly useful in industrial and commercial power-distribution systems where temporary voltage dips may occur and immediate circuit-breaker opening is undesirable. Its dedicated Tmax XT compatibility and IEC/UL suitability make it a practical accessory for coordinated undervoltage protection systems.

Controlled Undervoltage Release Operation
An undervoltage release is used to open a circuit breaker when its control voltage falls below the required operating level. In installations where temporary voltage dips can occur, an electronic time delay can prevent an immediate response to short-lived disturbances while still allowing the undervoltage release to operate when the low-voltage condition persists.
The ABB UVD 1SDA101982R1 provides this delay function for compatible XT5 and XT6 undervoltage-release installations. Its 220–250 V AC/DC voltage range makes it suitable for industrial and commercial control systems based on the SACE Tmax XT circuit-breaker platform.
Typical Applications
- ABB SACE Tmax XT5 circuit-breaker installations.
- ABB SACE Tmax XT6 circuit-breaker installations.
- Undervoltage-release control systems.
- Industrial low-voltage switchboards.
- Commercial power-distribution assemblies.
- Electrical systems exposed to temporary voltage dips.
- Control systems using 220–250 V AC/DC supplies.
