This relay has been used for many years by Skutt Kilns. It fits KM models that have 5 louvered vents on the top of the control box. If yours has 6 then you should use the black relay.
As of 2011, Skutt recommends replacing your old clear 25 Amp with the same 25 Amp Relay that they were always using, instead of upgrading to the new black relays which are used in all new kilns. The old style clear Deltrol relays have turned out to do just as good a job if not better than the new black version. If you have any questions about this product feel free to call and speak with our kiln technician.
OEM part # 1517
