Description
xCurrent Transformer 100A:50mA for MultiPlus-II (1m) 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 connects via a 1-metre wire-end lead, making it suitable for monitoring AC input or output current in residential and light commercial installations.
Key Features
- 100A primary to 50mA secondary ratio, providing accurate AC current measurement for the MultiPlus-II.
- 1-metre wire-end lead for straightforward connection to the MultiPlus-II current sensing input.
- Compact and lightweight at 55g, suitable for installation within standard enclosures and distribution boards.
- Split-core or solid-core design allows the transformer to be clipped or threaded around the conductor without breaking the circuit.
- Compatible with Victron MultiPlus-II systems for grid current monitoring and energy management via GX devices.
Product Overview
The current transformer works by inducing a proportional secondary current from the primary conductor passing through its core. 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.
The 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.

Installation Notes
This 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.
