- Description
The UVR-C XT2-XT4 W 380-440 Vac undervoltage release, ABB 1SDA066407R1, opens withdrawable Tmax XT2 and XT4 circuit breakers automatically if the monitored 380-440 V AC supply drops or is lost. It is factory-wired for direct connection to the control circuit rather than supplied with loose leads for field wiring. EAN 8015644003173.

Selection Notes
Specify this undervoltage release where the breaker must open automatically on loss or sag of the 380-440 V AC supply, such as a safety-interlocked circuit; unlike a shunt release, it needs no external trip signal and reacts to the monitored voltage itself. It is factory-wired, so no field wiring of loose leads is required.
