Contactor K1321

Sale of high-frequency K1321 Contactors with air cooling. Warranty 1 year.

  K1321 contactors are designed for switching on and off of induction heating installations, including quenching and smelting, in medium frequency circuits from 500 to 10,000 Hz. K1321 contactors are designed for electrical networks with a rated main circuit voltage of up to 800 V with a frequency of -10000 Hz.

    K1321 series contactors operate in intermittent - continuous, continuous, short-time and short-time operation modes.

K-1321 contactors consist of a contact-switching electromagnet, arcing system, mobile system, auxiliary contacts and a base, a cooling system, as well as a rectifier device for contactors with alternating current control

   The arcing and contact system K 1321 consists of an arc chute, main and arc-extinguishing contacts connected in parallel and having silver-bearing pads. The electromagnetic system consists of a core, an armature and a coil.

    The control circuit coil consists of two windings: including and winding, connected in series. The contactor K1321 has three disconnecting and three normally open contacts of the auxiliary circuit.
