Like the 120A model it reports per-phase voltage, current, active and apparent power plus accumulated energy in real time, with support for 4-quadrant (import\/export) measurement for solar or battery installations. It connects over Wi-Fi, Bluetooth and LAN and supports Modbus TCP, MQTT and webhooks.\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 3EM-400A\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\u003e3-phase (or 1-phase) energy meter, DIN-rail mounted; Ships with 3x 400A split-core current transformers; Voltage measurement: 100-260V RMS per phase; Current measurement: 0-400A RMS per phase and neutral; Power supply: 110-240V AC, 50\/60Hz; Power consumption: \u0026lt;3W; Accuracy class B, 1% (IEC 62053-21); Data logging: at least 45 days at 1-minute resolution; Dimensions: 94x19x69mm; Weight: 62g; Operating temp: -20°C to 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Shelly","offers":[{"title":"Default Title","offer_id":49954604712165,"sku":"SHELLY PRO 3EM-400A","price":7539.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0010\/6725\/files\/Shelly-Pro-3EM-400-main-image.png?v=1783409573","url":"https:\/\/guardsondutyshop.co.za\/products\/shelly-shelly-pro-3em-400a","provider":"Guards On Duty Shop \u0026 Security Guards ","version":"1.0","type":"link"}
