Skutt Relay – 50 Amp – Single Phase for KM-1 Wall Mount
Skutt Part Numbers
Why does the KM-1 wall mount controller use a different style of relay than most other kilns?
The higher amperage requirements of the KM-1 wall mount controller dictates that it must use a contactor capable of handling the increased amperage.
The KM-1 wall mount controller uses a different style contactor than all other kilns. Instead of using a 12v dc signal to drive the main relay, all KM-1 controllers use a 240/208v ac signal to drive the main relay. Unfortunately the computer control board is not able to put out a signal with a high enough voltage to drive the main contactor so a small signal relay is used as well.
