Product details

The split core current transformers produce a scaled down AC current in the secondary windings that is directly proportional to the AC current in the primary conductor around which they are placed.

These transformers are safely and easily installed over existing electrical power lines without disconnecting lines or otherwise interrupting service.

The output to the Power Meter is in the mA range, and they have internal over-voltage protection to limit the maximum unburdened voltage output to a safe level.

They are designed to fit into confined spaces while the primary conductor is still live.

They are a compact design with a mechanical hinge for multiple opening and closing actions.
