Description


PRK motor-starters of IEK® trade mark are designed for managing and protecting three-phase asynchronous electric motors from overloads, short-circuit and open-phase operating conditions. They combine the functions of a modular circuit breaker serving for motor protection and a manual starter. These starters are used at industrial sites, agriculture and construction. It is possible to apply them for the local management of separate electric motors as well as residential and administrative building automation.

According to their constructive and technical features, PRK motor-starters meet the requirements of international standards IEC 60947-4-1, IEC 60947-5-1.

Design Features


PRK32 motor-starter can be locked with a padlock. Possible joint installation of two DK32 or DK32 and DK/AK32.
Possibility to increase the number of auxiliary contacts. All parts are protected from direct access.
Saving space and time at the installation. Easy and convenient adjustment of the thermal release setting range. TEST button is intended for checking PRK32 without its connection to the power circuit. Screw size provides for using one screw driver when dealing with power clamps and control circuit electric terminals.
Auxiliary and emergency contacts joined under one casing DK/AK32. Protective enclosure with a turn-push button
STOP and a transparent safety cover for a START button ensures IP54 protection degree.
