It is the genuine Raypak part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA contactor is a heavy duty relay. The control side of the unit sends a small signal to the contactor coil, the coil pulls a set of large contacts closed, and full line current flows through to the main load. Every heat cycle passes through those contacts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow it fails\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMaking and breaking high current arcs the contact faces. Over years they pit, carbon up, and either stop conducting or, at the other extreme, weld themselves shut. A heater that will not start when it calls for heat, or one that will not stop when it should, points straight at the contactor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUse the right part\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 50 amp rating is only part of the story. Coil voltage, terminal arrangement and mounting all have to match, which is why the Raypak part number is the sensible replacement rather than a generic contactor of the same amperage.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48627978830036,"sku":"RAY-151-1227","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_940feaf4-09b5-401a-962a-f2b3797e990d.jpg?v=1788732206","url":"https:\/\/www.activepoolsupply.com\/products\/raypak-h000043-50-amp-contactor-for-model-5100-6100-5100ti-pool-heaters","provider":"Active Pool Supply","version":"1.0","type":"link"}
