Description
On 208V three-phase a FIN heater switches through a contactor, and the FX303 is the one Finlandia specifies for that supply with an F-2T or F-2 control. The wall control stays the same; only the switching hardware changes with the phase.
Mount it in a dry, serviceable location outside the hot room. Wiring is a licensed electrician’s job — the heater manual has the diagram for your exact model.
Please note: to preserve the originality, operation and safety of replacement parts, contactors are not returnable.
