A relay can contain several changeover contacts. They are designed to transfer a house (or business) electricity from the commercial power grid to a local generator when n outage occurs. Also known as “transfer switches,” they connect directly to the generator, commercial power supply or line, and the house. The main difference between a relay and a switch is that a switch is operated mechanically while a relay is operated electrically.\u003c\/p\u003e","brand":"Hager","offers":[{"title":"Default Title","offer_id":51571010273595,"sku":"SFT440","price":455.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/3480\/8379\/files\/Hager-Centre-off-changeover-switch-on-off-on-4-pole-40A-Rubicon-Installer-Portal-27785063694476.png?v=1787259837","url":"https:\/\/gunmansa.co.za\/ru\/products\/hager-centre-off-changeover-switch-on-off-on-4-pole-40a","provider":"GUNMANSA","version":"1.0","type":"link"}
