ABB 1SDA101981R1 UVD XT5-XT6 110..125Va.c./d.c. Time Delay Under Voltage Coil Tmax XT

The ABB 1SDA101981R1 UVD XT5-XT6 110..125Va.c./d.c. is a time delay under voltage coil designed for use with ABB Tmax XT5 and XT6 moulded case circuit breakers. This accessory monitors supply voltage and introduces a controlled time delay before tripping the breaker on under-voltage conditions, protecting sensitive industrial equipment from damage caused by voltage dips or loss of supply. Compact and CE-certified, it integrates seamlessly into control panels and industrial automation systems.
