This unit produces a 50mA output when 100A flows through the primary conductor, which the MultiPlus-II uses to measure current accurately without direct electrical connection to the high-current circuit. This isolation is both a safety feature and a practical advantage in installations where the measurement point is remote from the inverter.\u003c\/p\u003e\n\n\u003cp\u003eThe 5-metre cable allows the CT to be positioned at the point of measurement, such as at the main incomer or on a specific load circuit, while the MultiPlus-II remains mounted elsewhere in the installation. This is particularly useful in larger enclosures or where the inverter and metering point are physically separated. The CT is not a general-purpose unit; it is matched to the MultiPlus-II's input requirements and should only be used with compatible Victron equipment.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRatio: 100A : 50mA\u003c\/li\u003e\n  \u003cli\u003eCable length: 5 metres\u003c\/li\u003e\n  \u003cli\u003eCompatible device: Victron MultiPlus-II\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.085 kg (85g)\u003c\/li\u003e\n  \u003cli\u003eSKU: CTR110000550\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076054634\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 MultiPlus-II installations for accurate power management.\u003c\/li\u003e\n  \u003cli\u003eLoad current measurement in off-grid and hybrid solar systems using the MultiPlus-II.\u003c\/li\u003e\n  \u003cli\u003eResidential and light commercial battery storage systems where AC current feedback is required by the inverter\/charger.\u003c\/li\u003e\n  \u003cli\u003eRetrofit installations where a CT was not included with the original MultiPlus-II supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Current Transformer 100A:50mA with 5m cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis CT must be installed by a qualified electrician. It should be fitted around a single AC conductor only; placing it around multiple conductors or a twin-and-earth cable will produce an incorrect or zero reading. Ensure the cable is routed and secured so it cannot be damaged by heat, sharp edges or moving parts. Connection to the MultiPlus-II should follow Victron's wiring guidelines for the specific installation. For grid-connected systems in the UK, the overall installation must comply with G98 or G99 requirements as applicable.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47441554833742,"sku":"CTR110000550","price":21.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/current-transformer-100a50ma-for-multiplus-ii-5m-ctr110000550-752713.jpg?v=1747937072","url":"https:\/\/voltaconsolar.com\/products\/current-transformer-100a-50ma-multiplus-ii-5m","provider":"VoltaconSolar","version":"1.0","type":"link"}
