Finlandia / Harvia Part # FH73 or ZSK-778 Contactor ABB AF16-40-00-13, 240v coil is the dedicated power-switching relay that keeps compatible sauna heaters operating safely and reliably. Matched to a 240V coil, it allows low-voltage controls to command high heater loads without overstressing internal switches.

Whether replacing a worn relay or completing a new installation, it is a critical component for dependable, code-conscious sauna heater operation.
