Contactors of alternating current KT6030/2, KT6030/3

Contactors of alternating current KT6030/2, KT6030/3 - KT6033, KT6032, KT-6033, KT-6032

Electromagnetic contactors of alternating current are designed to remotely turn on receivers of electrical energy (frequent start-up of electric motors with a squirrel-cage rotor, deactivating rotating and moving electric motors, and counter-current braking).

 Name                Rated current, A               Voltage, V            Number of poles          Mass, kg

 КТ6030 / 3                  250/200                     220/230                      2 - 3                               18

 КТ6030 / 2                  250/200                          380                          2 - 3                               18

The rated voltage of the main circuit of KT6030 / 3 contactors is 220 V DC, KT6030 / 2 contactors is 380 V AC at 50 and 60 Hz. Installation of contactors on metal frames of control stations; universal design, allowing both front and rear connection of wires and tires. It is allowed to install contactors on insulating plates using remote pads. The frequency of switching contacts - 60 per hour. Mechanical and switching durability of contactors - 0.025 million cycles. Auxiliary contacts of contactors are made with two closing (3) and two opening (P) or three closing (3) and three opening (P) contacts, which do not allow the contacts to be replaced in operation. The magnetic system of contactors - with switching coils, designed to power from both AC and DC. The nominal voltage of the switching coils of contactors of general purpose and cold-resistant, intended for operation in the country is 48, 110, 220 V DC and 110, 127, 220, 380 and 500 V AC 50 Hz. The nominal voltage of the switching coils of contactors of general purpose and tropical design, intended for export delivery, is 48, 110, 220 V DC; 110, 127, 220, 230, 240, 380, 400, 415 V AC in the frequency of 50 Hz; 110, 220, 380, 440 V, frequency 60 Hz. Contactors have a snap mechanism. Electromagnetic contactors KT6030 / 2 are designed for continuous operation in the absence of voltage in the supply circuit of the switching coil. In tropical design, the contactors are suitable for operation in electrical circuits with a voltage of 400, 415 V, frequency 50 Hz and 440 V, frequency 60 Hz. Contactors are available in two-and three-pole versions with closing (3) main contacts. For contactors of climatic versions “U”, “CL” the rated current of the main contacts is 250 A; for climatic version “T” - 200 A. Electromagnetic contactors KT6030 / 3 are designed to extinguish the field of synchronous machines, as well as for operation in circuits where it is unacceptable to disconnect the contactor in the absence of voltage in the supply circuit of the closing coil.
