KREPTA 3 Plastic empty enclosure with door 4 modules IP30

KMI AC contactors with thermal electrical relay in a protective enclosure represent a complete device consisting of a compact contactor KMI, RTI thermal electrical relay, enclosure with glands and control buttons. Intended for remote actuation by means of direct connection to the network and shutting down three-phase asynchronous electric motors with a short-circuited rotor for the applied voltage limited to 400 V as well as for protecting electric motors from overloads of inadmissible duration and overcurrents arising in case of one phase retardation. Applying KMI 10910 + KMI 23211 contactors predetermines the use of a plastic enclosure; KMI 34012 + KMI 49512 are supplemented with a metal one. Correspond to the requirements of EN 60947-1, EN 60947-4-1, EN 60947-5-1.
