Contactor kmi 11860

Contactor KMI-11860 18A in a 220V, 380V IEK enclosure in a plastic case with Start and Stop buttons.

A small-sized AC contactor for general industrial use KMI for a load current of 18 A is designed to start asynchronous electric motors with a squirrel-cage rotor for voltages up to 660V. All versions for load current up to 40A have one group of make or break additional contacts. Executions for load current over 40A & mdash; two groups (closing and opening). Contactors allow remote control of lighting circuits, switching three-phase capacitor banks and primary windings of three-phase low-voltage transformers. Contactor KMI-11860 design and principle of operation KMI 11860 contactors are electromagnetic alternating current devices, the magnetic systems of which are divided into two parts: fixed, elasticly fixed in a plastic base, and movable with contacts for switching the power circuit. The operation of the contactor is controlled by an electromagnetic inductor located on the middle rod of the stationary part of the W-shaped magnetic system. Principle of operation: under the influence of the electromagnetic field of the retractor coil, which occurs when current flows through it, the magnetic system closes and the counteraction of the return spring and the springs of the contact bridges is overcome. To prevent detonation, massive short-circuited aluminum rings are provided, pressed into the pole pieces of the stationary part of the magnetic system. Advantages: wide area of ​​application of KMI 11860 contactors, significant operating temperature range from -40 °; up to + 50 ° С Notches on the connecting clamps, excluding overheating and melting of the wires due to reliable fixation at the connection points Convenience of replacing the pick-up coil Versions for ten rated currents Service life not less than 15 years Contactor KMI-11860 technical characteristics Open version contactor without housing Rated current 18A Coil voltage KMI-11860 -400 V Additional contacts-1 normally open contact The contactor is equipped with a thermal relay of the RTI type. Reverse is not provided. Number of poles 3. Rated impulse voltage Uimp 6 kV. Conditional thermal current Ith (tgr & lt; 40gr), application category АС-1 32 A. Rated power according to АС-3, kW: 230 V & mdash; 4.400 V & mdash; 7.5. 660 V & mdash; 10. Maximum short-term load (t & lt; = 1s) 324 A. Conditional short-circuit current KMI 11860 Inc 3000 A.
