With Wi-Fi, LAN, and Bluetooth connectivity and a total switching capacity of 48A across its three 16A channels, it targets industrial and commercial automation where galvanically isolated switching is required rather than direct power measurement.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable border=\"1\" cellpadding=\"4\" cellspacing=\"0\" style=\"border-collapse:collapse;width:100%\"\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSHELLY PRO 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShelly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSmart Home\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eKey Specs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eChannels: 3; Max load: 16A per channel, 48A total; Contact type: potential-free (dry contacts), no power metering; Connectivity: Wi-Fi, 10\/100 Ethernet (LAN), Bluetooth; Power supply: 110-240V AC; Mounting: DIN-rail (breaker box); Protections: temperature, overpower, overvoltage; Protocols: Shelly Gen2 RPC\/MQTT, local + cloud control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Shelly","offers":[{"title":"Default Title","offer_id":49954603106533,"sku":"SHELLY PRO 3","price":2339.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0010\/6725\/files\/Shelly_20Pro_203.jpg?v=1783409542","url":"https:\/\/guardsondutyshop.co.za\/products\/shelly-shelly-pro-3","provider":"Guards On Duty Shop \u0026 Security Guards ","version":"1.0","type":"link"}
