Description
xCurrent Transformer 100A:50mA for MultiPlus-II (5m) Wire-end
This current transformer is designed for use with the Victron MultiPlus-II inverter/charger to measure AC current up to 100A. It outputs a 50mA signal and comes with a 5-metre wire-end lead, allowing it to be positioned at the point of measurement and wired directly into the monitoring circuit without additional connectors.
Key Features
- 100A primary to 50mA secondary ratio, suitable for measuring mains or generator AC current in MultiPlus-II installations.
- 5-metre cable length provides flexibility in positioning the transformer relative to the MultiPlus-II unit.
- Wire-end termination for direct connection to the MultiPlus-II current sensing input.
- Compact, clip-on split-core or solid-core design for installation around a single conductor.
- Lightweight at 85g, making it straightforward to mount in a distribution board or enclosure.
- Compatible specifically with the Victron MultiPlus-II series for accurate current monitoring and grid management functions.
Product Overview
The MultiPlus-II uses current transformer inputs to monitor AC current on the grid or generator connection. This allows the inverter to implement functions such as PowerControl and PowerAssist, where the unit must know how much current is already being drawn before deciding how much to add or limit. Without an accurate current reading, these features cannot operate correctly.
The 100A:50mA ratio is matched to the MultiPlus-II's input specification. The 5-metre lead gives installers enough reach to route the cable neatly from the measurement point, typically around the incoming live conductor at the consumer unit or distribution board, back to the MultiPlus-II terminals. The wire-end finish means no additional adaptor is needed; the wires connect directly to the designated CT terminals on the unit.

Installation Notes
This current transformer must be installed by a qualified electrician. It is fitted around a live AC conductor, which requires safe isolation procedures and compliance with BS 7671 wiring regulations. For grid-connected MultiPlus-II systems, the installation must also meet G98 or G99 requirements as applicable. Ensure the CT is connected to the correct terminals on the MultiPlus-II as specified in the Victron wiring documentation. Do not install the transformer around a bundled twin-and-earth or multi-conductor cable; it must encircle a single conductor only.
