KB-1-250-3B3 250A 1140B, coil 220B

Contactors the vacuum KB1 series are intended for use in actuators, stations of management, for switching of currents of inclusion and shutdown of asynchronous electric motors with a short - circuited rotor and other loads in remote control systems electric drives. Prime areas of application - metallurgical, oil and gas, mining, urban and railway transport and other industries with heavy operating modes of electric drives. Letters in structure of designation of contactors mean: Р - the reversing contactor with mechanical blocking; With - the contactor of special execution. Kontaktora of general purpose with direct current coils can have execution with the block of clips established from above or on the right that needs to be specified in addition at the order. Contactors have execution with the electronic component of a forsirovka for a power supply of coils alternating current and execution with the pilot relay for a power supply of coils a direct current or alternating current via the rectifier established from below or at the left that needs to be specified in addition at the order. The reference document - TU 3426 - 016 - 00213703 - 96.
