Rated operation power at AC-3, 400 V: 18,5
Rated operation current Ie: 60
Conditioned rated short-circuit current Iq: 3
Setting range over-current release: 30...40
Connection type main current circuit: EV000415

.
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.
