  • Description

Built for fixed or plug-in Tmax XT5-XT6 molded case circuit breakers, the ABB 1SDA104959R1 (YU-C XT5-XT6 F/P) is a wired undervoltage release that trips the breaker automatically if the AC supply voltage collapses, preventing an unmonitored load from re-energizing on its own. Its coil is rated 380...440 V AC, and the part weighs 0.123 kg.

Selection Notes

The F/P designation fits this undervoltage release to fixed and plug-in Tmax XT5-XT6 breakers rather than the withdrawable (W) frame used by the other 380...440 V AC variant in this range. As with any YU release, it trips the breaker on loss of supply voltage, preventing an unmonitored load from re-energizing automatically once voltage is restored.
