Description
xCurrent Transformer 400A:50mA for MultiPlus-II (10m) Wire-End
This current transformer is designed for use with the Victron MultiPlus-II inverter/charger, providing accurate AC current measurement via a 10-metre wire-end connection. It is intended for professional installers who need to monitor grid or generator current as part of a managed energy system.
Key Features
- 400A:50mA ratio provides accurate current sensing across a wide load range.
- 10-metre cable length gives flexibility in panel and enclosure placement without extension wiring.
- Wire-end termination for direct connection to compatible Victron monitoring inputs.
- Designed specifically for use with the Victron MultiPlus-II inverter/charger range.
- Compact and lightweight at 0.25 kg, suitable for installation in standard distribution boards and enclosures.
- Split-core or solid-core design allows installation around existing conductors without breaking the circuit.
Product Overview
Current transformers (CTs) are used to measure alternating current in a conductor by producing a proportional secondary current, in this case 50mA at full 400A primary load. This signal is fed to the MultiPlus-II's CT input, enabling the inverter to monitor grid import and export in real time. Accurate current measurement is essential for correct power assist, grid feed-in control and ESS (Energy Storage System) operation.
The 10-metre cable length is a practical advantage in installations where the metering point is some distance from the inverter or GX device. This avoids the need for field-spliced extensions, which can introduce signal errors. The wire-end format means the installer connects directly to the designated terminal on the MultiPlus-II without requiring an intermediate connector.
This CT is a required accessory for MultiPlus-II installations where grid current monitoring is needed, particularly in ESS configurations where the system must track net grid power to manage charge and discharge behaviour correctly.

Installation Notes
This current transformer must be installed by a qualified electrician familiar with Victron MultiPlus-II systems and ESS configuration. The CT must be clipped around the correct conductor (typically the grid live feed) and oriented in the correct direction as specified in the MultiPlus-II installation manual. Incorrect orientation will result in reversed current readings and improper system behaviour. For grid-connected ESS installations in the UK, the system must comply with G98 or G99 requirements as applicable. Do not install around bundled or multi-core cables containing more than one current-carrying conductor.
