The SW182B features single-pole double-breaking main contacts with silver alloy tips, which are weld resistant, hardwearing and have excellent conductivity.\u003cbr\u003e The SW182B main contact circuit, designed for motor reversing, is such that it has a built-in failsafe, so that if both coils are energized simultaneously the contact arrangement is open circuits.\u003cbr\u003e The SW182B has M8 stud main terminals and 6.3mm spade coil connections. Mounted using the supplied bracket, mounting of the solenoids can be horizontal or vertical, when vertical the M8 contact studs should point upwards.\u003cbr\u003e\u003ctable id=\"arc_part_info2\" cellspacing=\"3\" cellpadding=\"2\" border=\"0\"\u003e\t\u003ctbody\u003e\t\t\u003ctr\u003e\t\t\t\u003ctd class=\"ArcTableDark\"\u003e\n\u003cspan style=\"color:#484848\"\u003e\u003cstrong\u003eInterrupted\u003c\/strong\u003e\u003c\/span\u003e current - opening and closing on load with frequent switching - results in increased contact resistance).\u003c\/td\u003e\t\t\u003c\/tr\u003e\t\t\u003ctr\u003e\t\t\t\u003ctd class=\"ArcTableDark\"\u003e\n\u003cspan style=\"color:#484848\"\u003e\u003cstrong\u003eUninterrupted\u003c\/strong\u003e\u003c\/span\u003e current - no or infrequent load switching requirements - maintains a lower contact resistance).\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eMagnetic Blowouts\u003c\/h4\u003e These contactors are fitted with magnetic blowouts - denoted by 'B' suffix in the SW182B range) across contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts can make the contacts polarity sensitive and the positive markings on the top cover of the contactor must be observed.","brand":"Albright","offers":[{"title":"Default Title","offer_id":56974489125196,"sku":"101-SW182B-4","price":206.7,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/6723\/6172\/files\/SW182B-4.jpg?v=1773426331","url":"https:\/\/mkcontrols.eu\/products\/sw182b-4-albright-150a-150a-24v-dc-co-2-x-sw181-motor-reversing-contactor","provider":"MKCONTROLS.EU","version":"1.0","type":"link"}
