Installation Contactors
IK, IKA, IKD
 | Installation contactors are applied for automatic control of electric devices in installations of dwelling, offices, shops and hospitals. They are particulary suitable for switching lighting, heat pumps, air-conditioning and similar equipment and are also intended for switching single phase and three phase electric motors. They excel in silent operation. Contactors can be built in electric distribution panels on 35 mm mounting rails (in compliance with EN 60715). Sealing of a contactor cover is also possible. IKD20, IKD25, IK40 and IK63 are DC driven contactors with overvoltage protection and with a rectifier which enables DC or AC voltage control. Four make contacts of a contactor can be applied as main or auxiliary contacts. IKA20, IK21 and IK25 are AC driven contactors only. Special version IKA/IKD 20/25-R are with manual operating mechanism (override function). An auxiliary switch with two contacts can be attached:
