07.01 Contactors

KMI AC contactors of general industrial purpose are designed for load currents from 9 to 95A (AC-3). Intended for actuating, shutting down and reversing of asynchronous motors equipped with a short-circuited rotor for the applied voltage limited to 660V, 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 per load currents limited to 40A have a single group of auxiliary NO or NC contacts. Types per load currents exceeding 40A have two contact groups (NO and NC). KMI AC contactors 9-95A application includes fan, pump, thermal curtain, furnace, overhead-track hoist, unit, lighting and automated load transfer systems control.

Electromagnetic contactors of KTI series are intended for use in control circuits for start and stoppage of 3-phase squirrel-cage induction motors supplied from mains with rated voltage up to 660V, and also can be used for switching on/off other electrical units: lighting, heating devices, various inductive loads. Used with fans, pumps, furnaces, beam cranes and automatic load transfer systems.

PM12 AC contactors for load currents from 10 to up 63A (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 (AC-3 application category). They can be also used for remote control of lighting, heating circuits and various low-inductance loads (AC-1 application category). All unit types per load currents limited to up 40A have a single group of auxiliary NO or NC contacts. Types per load currents exceeding 63A have two contact groups (NO and NC).

Mini contactors of MKI series are intended for use in control circuits of various loads supplied by AC voltage up to 660V, 50Hz. The mini contactors allow for remote switching of power circuits of application categories AC3 (control of motors up to 5kW) and AC1 (control of heaters). The mini contactors enclosures ensure degree of protection IP20 according to GOST 14254. The climatic version and application category of the contactors is UHL4 according to GOST 15150.
