Contactors and relays

Contactors

Ex9C Series contactors are primarily intended for industrial applications. They comply with the requirements of IEC / EN 60947-4-1. These contactors are provided in three sizes. Size 18 covers nominal currents of 9, 12 and 18 A in utilisation category AC-3. Size 38 is intended for 25, 32 and 38 A versions. Size 100 is then available with nominal currents of 80 and100 A. Thus, application to three-phase motors up to 45 kW can be fully covered. The agreed-on Ith thermal current of these contactors is 125 A.

Devices can work up to the voltage of 690 V AC. Coil control voltage is optional within the range from 24 up to 415 V AC. Contactors are three-phase designed with integrated auxiliary contacts 11 or 22.

Ex 9C Series contactors can be fitted with one front auxiliary contact unit (including two or four contacts) and with one left-hand and one right-hand side contact unit. Further, they can be combined with Ex9R38 and Ex9R100 overload relays.
