The contactor kmi 11810 is designed to control three-phase asynchronous electric motors with a squirrel-cage rotor, control fans, pumps, DC motors, transformers, heat guns, furnaces, cranes, machine tools, lighting systems. Installed both on a DIN rail and with screws. The working position is vertical. The operation of the KMI 11810 contactor is controlled using a multi-turn magnetic coil located on the middle rod of the stationary part of the magnetic system of the contactor. To reduce the force of blows in the magnetic circuit when the contactor is triggered, special short-circuited aluminum rings are pressed into the pole pieces of the stationary part of the magnetic system. These rings create an electromagnetic force against the movement of the moving part of the magnetic circuit of the contactor and, therefore, reduce the force of impact. Contactors kmi 11810 technical characteristics Operating current 18A, Power of the connected motor 4-10kW (at 230-660V), Maximum load 324 A, Conditional short-circuit current 3000A, Dissipation power of the contactor kmi 11810 - 2 W, Response time 70-80 ms (short circuit ) 15-20 ms (opening), Switching durability 1.4 Million cycles, Mechanical durability (no load) 2 Million cycles
