Used for company SC-4-1 main circuit contact protection

The contents are the CR snubber of delta connection. Since it has 3 terminals, it is a line-to-line connection, connection between contacts is not assumed. Although it contributes as a surge energy reduction effect in suppressing spark between contacts, since the spark itself can not be completely suppressed, in normal usage it will be extension of contact life. By the way, when I tried SC-4-1 in a high temperature and humid environment in a sulfide atmosphere, the contact life increased by 2 to 4 times. It seems that it is a result that the energy rise of the spark generated at the contact point is reduced and the temperature rise is suppressed. I think that there is no loss after trying it before responding with non-contact point and sealing of the board.
