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
