This data feeds into the PowerControl and PowerAssist functions, allowing the MultiPlus-II to limit its own current draw or supplement supply without overloading the incoming connection. Accurate current sensing is therefore a functional requirement, not an optional extra.\u003c\/p\u003e\n\n\u003cp\u003eThe 100A:50mA ratio is suited to single-phase supplies up to 100A, covering the majority of domestic and small commercial installations. The 20-metre cable length is a practical consideration: in many installations the inverter is located in a utility room or garage while the consumer unit is elsewhere, and a short cable would not reach. This variant eliminates the need for cable extensions that could introduce measurement error.\u003c\/p\u003e\n\n\u003cp\u003eThe wire-end format means the installer connects directly to the CT input terminals on the MultiPlus-II. No proprietary connector is required at the device end, keeping the installation straightforward.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CTR120002050\u003c\/li\u003e\n  \u003cli\u003eRatio: 100A:50mA\u003c\/li\u003e\n  \u003cli\u003eCable length: 20 metres\u003c\/li\u003e\n  \u003cli\u003eTermination: Wire-end\u003c\/li\u003e\n  \u003cli\u003eCompatible device: Victron MultiPlus-II\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.7 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076059097\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGrid current monitoring on single-phase MultiPlus-II installations in domestic properties.\u003c\/li\u003e\n  \u003cli\u003eGenerator input current sensing for PowerControl operation in off-grid or backup power systems.\u003c\/li\u003e\n  \u003cli\u003eLight commercial installations where the MultiPlus-II is used for energy management alongside a grid connection.\u003c\/li\u003e\n  \u003cli\u003eRetrofit installations where the inverter and consumer unit are separated by a significant distance.\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 20-metre wire-end cable\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 on the AC input of a Victron MultiPlus-II and must be fitted around the correct conductor in accordance with Victron's wiring documentation for that unit. Incorrect installation will result in inaccurate current readings and may affect the operation of PowerControl and PowerAssist functions. For grid-connected systems in the UK, the overall installation must comply with G98 or G99 requirements as applicable. Do not install on conductors carrying voltages or currents beyond the rated specification of the transformer.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863678484814,"sku":"CTR120002050","price":39.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CTR120002050_-_Current_Transformer_100A-50mA_for_MultiPlus-II_20m_Wire-end.webp?v=1781183311","url":"https:\/\/voltaconsolar.com\/products\/current-transformer-100a-50ma-multiplus-ii-20m","provider":"VoltaconSolar","version":"1.0","type":"link"}
