At a 100A:50mA ratio, it scales down the measured current to a safe, low-level signal that the MultiPlus-II can read directly. This allows the inverter\/charger to monitor grid or load current and adjust its behaviour accordingly, for example when using the PowerControl or PowerAssist functions to prevent overloading the grid connection or generator.\u003c\/p\u003e\n\n\u003cp\u003eThe 1-metre wire-end lead gives enough reach to route the signal cable neatly from the current transformer, clamped around the live conductor, back to the MultiPlus-II terminals. The wire-end termination means no additional connector is required at the transformer end, keeping the installation straightforward. At 55g, the unit adds negligible weight to the installation and fits comfortably inside a standard consumer unit or enclosure.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CTR120000500\u003c\/li\u003e\n  \u003cli\u003eRatio: 100A : 50mA\u003c\/li\u003e\n  \u003cli\u003eLead length: 1 metre\u003c\/li\u003e\n  \u003cli\u003eTermination: Wire-end\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.055 kg (55g)\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076059073\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAC current monitoring on MultiPlus-II installations for PowerControl and PowerAssist operation.\u003c\/li\u003e\n  \u003cli\u003eGrid input current sensing in residential solar-plus-storage systems.\u003c\/li\u003e\n  \u003cli\u003eGenerator current monitoring in off-grid and backup power setups using the MultiPlus-II.\u003c\/li\u003e\n  \u003cli\u003eEnergy management in light commercial installations where AC load current must be tracked by a GX device.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Current Transformer 100A:50mA with 1m wire-end lead\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis current transformer must be installed by a qualified electrician. It is intended for use with the Victron MultiPlus-II and should be fitted around the appropriate AC conductor in accordance with Victron's wiring guidelines for that product. Ensure the conductor passing through the transformer core carries no more than the rated 100A continuous. Do not connect to any other inverter\/charger model without confirming compatibility. All AC wiring work in the UK must comply with BS 7671 (18th Edition Wiring Regulations) and, where applicable, G98 or G99 requirements for grid-connected systems.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59855392375118,"sku":"CTR120000500","price":19.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CTR120000500_-_Current_Transformer_100A-50mA_for_MultiPlus-II_1m_Wire-end.webp?v=1781094268","url":"https:\/\/voltaconsolar.com\/products\/current-transformer-100a-50ma-multiplus-ii-1m","provider":"VoltaconSolar","version":"1.0","type":"link"}
