ABB 1SDA104951R1 Accessory - Under Voltage Release XT5XT6
Part Number: 1SDA104951R1
Quick Summary
Under Voltage Release for Tmax XT serves as a safety accessory that ensures reliable tripping when supply voltage falls, protecting motors and feeders in industrial power distribution. For engineers and maintenance teams, a nuisance trip during peak load is costly and disruptive, complicating startup sequences and compromising process uptime. This ABB accessory is designed for XT5 and XT6 withdrawable circuit-breakers, with proven compatibility for AC/DC control voltages and a compact, configurable interface. It carries CE declaration and is aligned with IEC60947-2 and UL489 standards, alongside RoHS, REACH, and TSCA declarations for responsible sourcing. By integrating the unit early in the design, procurement is simplified and lifetime operating costs are reduced through safer, more predictable switching.
