Description
Undervoltage release UA1 releases the manual motor starter or prevents it from being switched on when its voltage supply is interrupted. This can be used in emergency switching circuits or can prevent an automatic restart after voltage interruption. UA1 is attached laterally on the left side of MS116, MS132 or MS165 manual motor starters.
