1SAM201904R1005

ABB 1SAM201904R1005 UA1-230 is a 230 V AC 50 Hz / 240 V AC 60 Hz undervoltage release designed for ABB manual motor starters and MPCBs. It mounts on the side of the motor-protection device and automatically releases the starter when its control voltage is lost. This makes it suitable for no-voltage protection, emergency switching circuits, machine safety interlocking, MCC panels and applications where automatic motor restart after a power interruption must be prevented.
