3-in-1 Split Core Current Transformer – 100–250A, 1A / 5A Secondary

This 3-in-1 Split Core Current Transformer integrates three current transformers within a single compact housing, enabling efficient three-phase current measurement in commercial and industrial electrical systems.

Designed for 100A to 250A primary conductors, the unit provides 1A or 5A secondary output options for compatibility with standard energy meters and protection devices.

The integrated three-phase configuration simplifies installation, reduces wiring complexity, and minimises panel space requirements compared to installing three separate CTs.

Suitable for:

• Three-phase energy meters

• Power analysers

• SCADA and PLC monitoring systems

• Building Management Systems (BMS)

• Industrial IoT gateways

• Load balancing and demand monitoring

Operating at 50–60Hz, the transformer maintains a phase angle error of less than 2° at 50% rated current, supporting accurate energy profiling and system diagnostics.

The split-core design allows non-intrusive installation without disconnecting existing conductors, making it ideal for retrofit upgrades and operational facilities.

Typical applications include:

• Commercial distribution boards

• Manufacturing plants

• HVAC and plant equipment monitoring

• Solar inverter AC monitoring

• Generator output measurement
