Kiln contactor protection circuit

The coil of each kiln contactor should be suppressed with an RC circuit. RC circuits must be connected directly across the
coil terminals on each contactor. ROHDE kilns are delivered this way as standard. For kilns from other manufacturers,
suitable products are available as accessories from contactor manufacturers.
