Description
xCurrent Transformer 100A:50mA for MultiPlus-II (5m)
This current transformer is designed for use with the Victron MultiPlus-II inverter/charger, providing accurate AC current measurement via a 5-metre cable. It outputs a 50mA signal proportional to the measured current up to 100A, allowing the MultiPlus-II to monitor grid or load current for energy management and control functions.
Key Features
- 100A primary to 50mA secondary ratio, providing a standardised signal for compatible Victron equipment.
- 5-metre cable length gives sufficient reach for most installation configurations without extension.
- Designed specifically for use with the Victron MultiPlus-II inverter/charger series.
- Clamp-style transformer fits around a single AC conductor without breaking the circuit.
- Lightweight at 85g, making it straightforward to route and secure within an enclosure.
- SKU CTR110000550, GTIN 8719076054634, supplied by Victron Energy.
Product Overview
Current transformers (CTs) work by inducing a proportional secondary current when an AC conductor passes through the core. 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.
The 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.

Installation Notes
This 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.
