Spark Quencher's Calc


Recommended Posts

Dear All,


We have an old machine which has a PLC in its control panel. There is no protection for hard contacts of PLC out put relays. We want to connect “Spark Quencher “with parallel of contactors/relays coils which are operating through PLC out put relays.

Can anyone guide me how to calculate the rating of Spark Quencher?


Thanks in advance.
