Contact

Main and auxiliary contact, coil and auxiliary contact blocks are easily installed and removed. The coils of contactors are safely controlled between 0.8 and 1.1 times of their rated coil voltage. They operate at full performance in the ambient temperature of -5 and +55. The ability of assembling contactors to rails provides a great facility during installation. The ingredient of the material provides a resistance to an insulation vvoltage of 1000V.

Contactors damages and repairs

Contactor damages and effects of these damages:

There can be damages when the contactors are not used according to technical datas and then failures begin to occur at the feeding system. Reasons of probable cancellation of Contactors:

Generally, contactors are the devices, which do not damage easily. If the selection is made correctly and operating conditions are not out of order, contactor can make millions times opening and closing safely. The reasons of the cancellation and their solutions are given below.

Excessive length of cable of command circuit (coil) can cause some problems. Voltage is low during the long cables and this reason makes the closing difficultly and over big cross-sectioned cable capacitance obstruct opening. Generally advised cable cross-selection and length are mentioned in catalogues. If the command circuit is longer than the advised value, higher contactor and more lower coil voltage, resistance or inductive impedance connection should be used.

Dirt or foreign particles in the contactor, hard atmosphere conditions and corrosion can obstruct the closing operation of contactor. If we face a problem like this, contactor should be cleaned, appropriately. Then the circuit should be checked and modified for a more protective environment for the contactor. If there is a factor damaging the conduction, it should be removed.

Events that can cause the contactors, noisy operation is dust and having foreign particles in the air space etc, unsuitable voltage and frequency. Also defect of the nucleus surface because of long time operation. To obstruct all these, we should provide the clearness of the nucleus face and (if needed) coil changing should be made for voltage and frequency.

Changing the coil

New coil is put on by pulling up screws, which are taking place on both sides of the contactor, separating the upper parts and taking the coil out off its socket. Much attention should be paid to placing on its spring that at the bottom side, during re-assembling.
