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.
Attention!
If the contactors are not suppressed by a varistor, the controller can be damaged.
