KMI AC contactors of general industrial purpose are designed for load currents from 9 to 95 A (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 40 A have a single group of auxiliary NO or NC contacts. Types per load currents exceeding 40 A have two contact groups (NO and NC). KMI AC contactors 9-95 A application includes fan, pump, thermal curtain, furnace, overhead-track hoist, unit, lighting and automated load transfer systems control. Broadened range of KMI compact contactors as compared to the similar products from domestic manufacturers on Russian market. Wide range of optional devices readily available in the stock (PKI contact attachments, PVI time-delay attachments, RTI thermal relays). Installation on 35 mm DIN rail is possible (other domestic manufacturers offer this fixing only as optional feature). Reverse version can be obtained using the interlocking mechanism.
