Description
xCurrent Transformer 100A:50mA for Victron MultiPlus-II — CTR110002050
This current transformer (CT) is designed for use with the Victron MultiPlus-II inverter/charger. It provides accurate AC current measurement by stepping down a 100A primary current to a 50mA secondary signal, enabling the MultiPlus-II to monitor grid or load current without direct high-current wiring into the monitoring circuit. It is suited to professional solar and off-grid installations where precise current sensing is required.
Key Features
- 100A:50mA ratio provides accurate current measurement for the MultiPlus-II monitoring input.
- 20-metre cable length gives sufficient reach for installations where the inverter and metering point are not co-located.
- Designed specifically for compatibility with the Victron MultiPlus-II inverter/charger range.
- Clamp-style transformer fits around an existing conductor, requiring no break in the primary circuit.
- Weight of 0.7 kg indicates a robust, well-constructed unit suitable for permanent installation.
- Available while stocks last — this product is not being replenished once current stock is exhausted.
Product Overview
Current transformers are used in AC metering and protection circuits to produce a reduced, proportional current that can be safely measured by monitoring equipment. This unit uses a 100A:50mA ratio, meaning a 100A flow in the primary conductor produces a 50mA signal on the secondary side. This keeps the measurement circuit isolated from the high-current primary wiring, which is both safer and more practical in a panel or enclosure environment.
The 20-metre cable allows the CT to be positioned at the point of measurement (for example, at the main distribution board or grid connection point) while the MultiPlus-II is mounted elsewhere in the installation. This is particularly useful in larger residential or light commercial installations where equipment is spread across different locations.
This product is listed as available until stock reaches zero and will not be reordered. Installers who rely on this specific CT for MultiPlus-II installations should factor this into procurement planning.

Installation Notes
This current transformer should be installed by a qualified electrician familiar with Victron MultiPlus-II systems. The CT clamps around the primary conductor and must be correctly oriented and positioned to give accurate readings. Ensure the secondary circuit (50mA output) is connected to the correct input on the MultiPlus-II before energising. Do not open-circuit the secondary winding while the primary is live. For grid-connected systems in the UK, all work must comply with BS 7671 and relevant G98 or G99 requirements.
