Mounting can be in the motor, in the conduit box, or remote from the motor. Calibrated in one position for a specific pick-up and drop-out, the HLR3700 remains within tolerance in all other mounting positions. A variety of mounting brackets, terminals and assembly screw extensions are available to meet any mounting requirements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection data-element_type=\"section\" data-id=\"3e83677\" class=\"elementor-section elementor-top-section elementor-element elementor-element-3e83677 elementor-section-boxed elementor-section-height-default elementor-section-height-default\"\u003e\n\u003cdiv class=\"elementor-container elementor-column-gap-default\"\u003e\n\u003cdiv data-element_type=\"column\" data-id=\"f864aa2\" class=\"elementor-column elementor-col-66 elementor-top-column elementor-element elementor-element-f864aa2\"\u003e\n\u003cdiv class=\"elementor-widget-wrap elementor-element-populated\"\u003e\n\u003cdiv data-widget_type=\"text-editor.default\" data-element_type=\"widget\" data-id=\"859a444\" class=\"elementor-element elementor-element-859a444 elementor-widget elementor-widget-text-editor\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cp\u003e\u003cstrong\u003ePick-Up and Drop-Out Ratings\u003c\/strong\u003e\u003cbr\u003eRatings indicated maximum pick-up and minimum drop-out current limits. Pick-up is the current through the relay coil required to close the relay contacts. Drop-out is the current through the relay coil at which the contacts open. A production relay of a given rating will have a pick-up and drop-out current within the rating limit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperation\u003c\/strong\u003e\u003cbr\u003eThe HLR3700 relay coil is in series with the main winding of the motor and the normally open contacts are in series with the start winding. When voltage is applied to the motor, the in-rush current of the main winding through the relay coil creates a magnetic force which rotates the armature. This action closes the relay contacts and energizes the motor start winding.\u003cbr\u003eAs motor speed increases, the current in the main winding and relay coil decrease to a point where the armature biasing spring force is greater than the decreasing magnetic force, and the armature rotates back to its original position. This opens the relay contacts and disconnects the start winding.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003cp\u003e\u003cimg src=\"http:\/\/www.zjhongli.com\/images\/upload\/Image\/HLR3700_main.jpg\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cdiv id=\"eJOY__extension_root\" class=\"eJOY__extension_root_class\" style=\"all: unset;\"\u003e\u003c\/div\u003e","brand":"Hongli Electric","offers":[{"title":"Default Title","offer_id":14426399146043,"sku":"HLR3700-1-734","price":15.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0091\/0458\/8859\/products\/HLR3700-734.jpg?v=1536370994","url":"https:\/\/www.goodspec.com\/tr-sd\/products\/hlr3700-1-734-motor-starting-relay","provider":"HONGLI ELECTRIC CO.,LTD","version":"1.0","type":"link"}
