Contactors Ex9C

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 and 100 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.

Ex9C 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.
