Ex9C contactors are intended for various applications including heavy industrial ones. Splitting into four
frame sizes brings optimisation of electrical parameters and mechanical dimensions. All these frame sizes share accessory auxiliary contacts. Overload relays Ex9R differ with the frame sizes in order to fit respective contactor’s of given rated current.
Frame size 18 contains contactor’s with rated currents AC-3 9, 12 and 18 A at 400 V. Size 38 consists of rated currents 25, 32, 38 A. Version 65 is split into currents 40, 50 and 65 A. Finally frame size 100 is covered with rated currents 80 and 100 A.
