Contactors are frequently applied for switching of lamp loads, fans or pumps in both utility as well as industrial areas.

Hielek’s contactors are very specific due to the applied operating coil and construction of the main contacts. All contactors with AC/DC coils ensure silent operation which is further enhanced by a low power consumption.

Optimal contacts and low heat dissipation guarantee a long lifetime of the contactor which is available in a wide range of characteristics.
