    2 Pole contactor heater connection
    I have a heater that uses a 2 pole contactor between the heater contorl and the power supply. The contactor is a White Rogers 90-249 40 FLA @ 277 VAC. There are no instructions on which pins to use on the contactor for power in, where to connect a ground and which pins to use to connect to the heater controler. The contactor is used on a SE-9 Suncore 9 Kw Sauna heater supplied by Great Saunas. They provide a wiring diagram connecting to the controler but there is no information on which pins to connect to on the contactor.

    There are two sets of contacts with a line side and load side. The side 1/4 inch push on tabs are for the control voltage.

    Ground is the metal base plate on most units.

    Note: make sure you have the proper control coil voltage
