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.
Owing to the push-button control station, this provides for assembling a simple control circuit.
Rated control supply voltage Us at AC 50HZ: 230
Rated control supply voltage Us at DC: -
Voltage type for actuating: EV000460
Rated operation power at AC-3, 400 V: 5,5
Rated operation current Ie: 25
Conditioned rated short-circuit current Iq: 1
Setting range over-current release: 9...13
Connection type main current circuit: EV000415
Degree of protection (IP): EV006419.
Correspond to the requirements of EN 60947-1, EN 60947-4-1, EN 60947-5-1.
There is one NO contact group built in the control coil module in the circuit of every contactor.
Applying KMI 10910 + KMI 23211 contactors predetermines the use of a plastic enclosure
KMI 34012 + KMI 49512 are supplemented with a metal one.
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.
