Split Core Current Transformers for Industrial Monitoring

A split-core CT uses a rigid ferromagnetic core that snaps around the conductor and outputs a proportional current signal, typically suited for fixed, well-defined conductor geometries. A Rogowski coil uses a flexible, air-core loop that wraps around irregular conductors or busbars, providing a millivolt output and covering very wide current ranges — up to 10,000 A — with no magnetic saturation risk.

Yes. The split-core design opens and clamps around an energized conductor, so installation requires no wire disconnection or power interruption. This makes them the preferred choice for retrofit projects in existing electrical panels, switchboards, and distribution systems where downtime must be minimized.

The product range covers Class 0.2S, Class 0.5, and Class 1 accuracy per IEC 61869-2 and IEC 61557-12. Class 0.2S suits high-precision revenue metering, Class 0.5 is appropriate for power monitoring and energy management, and Class 1 is suitable for general load monitoring and control applications.

Yes. The DC Split-Core Sensors are specifically designed for DC load current measurement, covering 50 A to 2000 A. They feature a split-core design for tool-free retrofit installation, color-coded Molex connectors, and RJ12 Plug & Play connection to the DIRIS Digiware system — suitable for industrial DC power and renewable energy installations.

The portfolio spans 5 A to 10,000 A across multiple sensor families. Rigid split-core models cover 5 A to 4,800 A, flexible Rogowski sensors extend from 20 A to 10,000 A, DC sensors cover 50 A to 2,000 A, and residual current transformers handle 5 A to 630 A — providing solutions for virtually every industrial measurement application.

Products across the range are certified to IEC 61869-2, IEC 61869-10, IEC 61557-12, IEC 61010-1, UL 61010, UL 2808, CSA-C22.2, and IEC 62020 depending on model. These certifications confirm compliance with North American and international safety, accuracy, and performance requirements for industrial measurement instrumentation.
