current transformer / dry / AC / compact
for energy meters
Min.: 0 A
Max.: 500 A
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 interrupting service.The ratio of the primary current to the secondary current is 3000:1 so the output 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 whilst the primary conductor is still live. They are compact design with a mechanical hinge for multiple opening and closing action.
