The NPSvoltage of the unit is fixed at 7%. When any of these faults occur the unit will de-energize. The relay will only re-energize if the supply voltage corrects itself. The unit will not react to a balanced voltage variation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRelay ON LED\u003c\/li\u003e\n\u003cli\u003eOutput 10A SPDT\u003c\/li\u003e\n\u003cli\u003eDetection of phase asymmetry\u003c\/li\u003e\n\u003cli\u003eInsensitive to regenerated EMF\u003c\/li\u003e\n\u003cli\u003eFastresponse to reverse phase sequence\u003c\/li\u003e\n\u003cli\u003eMonitoring relay for 3-phase voltage control\u003c\/li\u003e\n\u003cli\u003eMeasures if all 3 phases present and in sequence\u003c\/li\u003e\n\u003cli\u003eInsusceptible to balanced supply voltage variation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eDESCRIPTION\u003c\/td\u003e\n\u003ctd\u003ePhase failure \/ sequence relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCONTACT\u003c\/td\u003e\n\u003ctd\u003e10A SPDT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFUNCTION\u003c\/td\u003e\n\u003ctd\u003ePhase failure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRATED VOLTAGE\u003c\/td\u003e\n\u003ctd\u003e250V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMECHANICAL LIFE\u003c\/td\u003e\n\u003ctd\u003e10x106 cycles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePROTECTION INDEX IP\u003c\/td\u003e\n\u003ctd\u003eIP 20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOPERATING TEMPERATURE\u003c\/td\u003e\n\u003ctd\u003e-10 to + 50°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSTORAGE TEMPERATURE\u003c\/td\u003e\n\u003ctd\u003e-50 to + 85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDIMENSIONS (MM)\u003c\/td\u003e\n\u003ctd\u003e(H) 92 x (W) 36 x (D) 64 \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Electrodev","offers":[{"title":"Default Title","offer_id":50985630531831,"sku":"SF1110A","price":706.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/4878\/1559\/files\/Electro-SF1-K-phase_20failure-phase_20reversal_27cd73e4-3ece-4d33-94b1-06c330931dd8.jpg?v=1785412608","url":"https:\/\/shop.tuskrenewable.co.za\/products\/sf1-110vac","provider":"Tusk renewable energy","version":"1.0","type":"link"}
