RADE KONCAR CNKM 75

These CNKM contactors are equipped with early-make contacts.This special type of contact has the purpose of connecting for a very brief interval, 2-3ms, during the contactor closing, resistors which limit the connecting current of the capacitors. These resistors are then excluded when the closing operation is complete and the current capacity is conveyed to the main contacts. With this type of circuit, it is possible to obtain minor wear of the components of the system especially fuses and capacitors ensuring a longer life and better reliability.
