KMIp DC contactors with control coil

Description


KMIp DC contactors with control coil for industrial use designed for load current from 9 up to 32A (AC-3) are intended for actuating, shutting down and reversing of asynchronous electric motors equipped with a short-circuited rotor for the applied voltage limited to 660V. They can be also applied for remote control of lighting (AC-5a, AC-5b), heating circuits and various low-inductance loads (AC-1), switching three-phase capacitor batteries (AC-6b) and primary windings of three-phase low-voltage transformers (AC-6a). All unit types have a single group of auxiliary NO contacts.

Application area of these contactors includes controlling fan, pump, thermal curtain, furnace, overhead-track hoist, unit, lighting and automated load transfer systems; uninterruptible power systems; automation and security alarm protection devices; industrial unit management systems; switching three-phase capacitor batteries and primary windings of three-phase low-voltage transformers.

According to its constructive and technical features, KMIp DC contactors with control coil meet the requirements of international standards IEC 60947-4-1.

Advantages


  • Extended range of options available at the warehouse (PKI attachments, PVI time-delay attachments, RTI thermal electrical relay).
  • 35-mm DIN-rail installation option (other manufacturers provide such option only as customized variants).
  • Energy saving in case of applying a DC control coil.

Design Features


Special oval terminal contacts ensure a secure conductor fixation with tempered disk spring washers. Integrated auxiliary contacts (NO contact (1NO)).
Magnetic system construction reduces consumption. When in operating mode, the magnetic system ensures an optimum exploitation (no noise and boosted contact system reliability).
Notches on terminal contacts lower the wire heating owing to the secure fixation in places of connection and boosting the overall contact area.

There are two ways to install the contactors:

  • Fast DIN-rail mounting:

KMIp from 9 up to 32A (dimensions 1 and 2) 35 mm;

  • Screw installation onto a mounting panel or profile.
