{"product_id":"liftmaster-k71-b1ph-1","title":"LiftMaster K71-B1PH-1 Brake Solenoid Kit — 120\/240V, SL585U \/ SL595U","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K71-B1PH-1 is the brake-solenoid kit identified by the manufacturer for the documented 120\/240V SL585U and SL595U applications. LiftMaster’s support information expressly corrects this kit reference and distinguishes it from three-phase and 575V brake-solenoid kits. Select it using the operator’s complete nameplate, electrical configuration and brake arrangement. The motor supply label and the brake circuit must be checked together; a similar-looking solenoid or a shared operator family name is not enough to establish fit.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented SL585U \/ SL595U 120\/240V arrangement\u003c\/td\u003e\n\u003ctd\u003eVerify the installed brake and applicable service instructions.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSL595UL service documentation\u003c\/td\u003e\n\u003ctd\u003eManufacturer support correction identifies this kit; match the actual unit configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThree-phase brake arrangements\u003c\/td\u003e\n\u003ctd\u003eUse the separately specified kit; do not infer fit from a shared voltage number.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e575V equipment\u003c\/td\u003e\n\u003ctd\u003eDifferent brake-solenoid reference and electrical requirements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndividual solenoid versus full service kit\u003c\/td\u003e\n\u003ctd\u003ePackage scope differs; confirm what the repair actually requires.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInspect the Brake Mechanism and Electrical Supply Together\u003c\/h2\u003e\u003cp\u003eA brake that fails to release or hold correctly may have a mechanical fault, an electrical supply problem or both.
