Is it possible to mount a surge suppressor with LED (LAD4RCE) on the CA4KN**, low consumption DC control relay.
CA4KN** control contactor comes fitted with integrated surge suppressor (bidirectional diode), thus there is no need for an external surge suppressor.
However if the additional surge suppressor on the CA4KN22** is required, then it is possible to mount the suppressor (LAD4RCE).
If the additional surge suppressor with LED is being used just for indication to verify that power is applied to the contactor, it is advisable to use a normal LED as per the coil voltage, connected to the coil supply (A1- A2).
This will give the indication functionality as that of the additional external surge suppressor with LED, if that is what the only requirement is.
