Intelligent motorstarter with motor rotection function Sophisticated drive tasks require powerful and flexible device solutions.With the new MINISTART UG 9256 from DOLD you have a intelligent motorstarter with load monitoring for motors up to 4 kW. It combines up to six functions in a space saving compact enclosure with only 22,5 mm width. Besides the reversal function our intel- ligent motorstarter also offers a soft start / soft stop function, a current monitoring as well as a motor protection function and a galvanic separation by an all pole disconnec- tion when motor is switched off. Due to the integrated motor protection function separate motor protection switches are not necessary. A power protection switch takes over the wire- and short circuit protection of the whole system. An internal relay provides galvanic isolation of the power outputs. While the semiconductor control provides a soft motor start, the direction reversal takes place through relay switching.The hybrid relay thus combines the advantages of rugged relay technology with non-wearing semiconductor tech- nology. The user benefits from a significantly longer device service life and improved reliability. The integrated current monitoring protection enhances the system avail- ability even further. Your advantages reversing clockwise / anticlockwise, soft start, current monitoring or motor protection, galvanic separation, soft stop Space saving in switching cabinet due to a width of only 22,5 mm Simple and time-saving commissioning as well as user-friendly operation, optionally with motor protection Robust power semiconductors up to 1500V Increased system availability through over current protection Higher life time by hybrid building Energy saving by fast over current protection
