If a towel, robe or anything else lands on it, the switch cuts power to the heater straight away, and it won't let the heater start again until the item is taken off. It's the safety device Harvia recommends for commercial and shared saunas (gyms, spas, hotels, rentals), and it's what lets a sauna be started remotely through a compatible Harvia control unit under the IEC\/EN 60335-2-53 safety standard. Working as an alternative to the door sensor without the sauna having to be armed for remote start.\u003c\/p\u003e\n\u003cp\u003eIt's made by Harvia in Finland, comes in six sizes to suit different Harvia heaters, and is low-profile, so it hardly changes the look of your sauna.\u003c\/p\u003e\n\u003ch4\u003eChoose your model\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eSuits these heaters\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFE-220400\u003c\/td\u003e\n\u003ctd\u003e410L*220D*100H mm\u003c\/td\u003e\n\u003ctd\u003eHarvia KIP 6–9 kW, Vega 4.5–9 kW, TopClass 4.5–9 kW, Sound 9 kW, Figaro 7–9 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFE-350400\u003c\/td\u003e\n\u003ctd\u003e410L*350D*100H mm\u003c\/td\u003e\n\u003ctd\u003eHarvia Virta 7–11 kW, Virta Combi 7–9 kW, Virta Pro 13.5–16 kW, TopClass Combi 5–8 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFE-500500\u003c\/td\u003e\n\u003ctd\u003e510L*500D*100H mm\u003c\/td\u003e\n\u003ctd\u003eQube 9–15 kW, Qube Professional 18–24 kW, Concept R 9–15 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFE-D350\u003c\/td\u003e\n\u003ctd\u003eØ350*100H mm\u003c\/td\u003e\n\u003ctd\u003eHarvia Cilindro 7–11 kW, Cilindro Pro 10–13.5 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFE-D450\u003c\/td\u003e\n\u003ctd\u003eØ450*100H mm\u003c\/td\u003e\n\u003ctd\u003eHarvia Cilindro Pro 16.5–20 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFE-D530\u003c\/td\u003e\n\u003ctd\u003eØ530*100H mm\u003c\/td\u003e\n\u003ctd\u003eHarvia Legend electric 11–16.5 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eNot sure which one fits?
