KMI contactors with thermal electrical relay into protective enclosure

Description


KMI contactors with thermal electrical relay into protective enclosure represent a complete device consisting of a compact contactor KMI, RTI thermal electrical relay, enclosure with glands and control buttons. They are 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 400V 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.

Design Features


IP54 protection type enclosure provides for using this contactor at construction sites, paint and galvanizing plants (on condition the installations are placed under a weather hood). Factory control circuit allows avoiding on-site connection faults and reducing the mounting time limited only by connecting linear feeding conductors.
In most cases loads are represented by three-phase asynchronous motors of 400V. The above mentioned control system is recommended for application in order to reduce the costs and save the working time as the necessity of using the fourth neutral working conductor is excluded. When managing active loads (heating and lighting circuits) using a neutral conductor, it is recommended to use a 230V control circuit.
