0-10mA Output Protection Device Zero Sequence Current Transformer

PRODUCT OVERVIEW
B series open and close residual current transformer, 90 degrees open and close freely, can be used outdoors. It can be quickly installed and disassembled in the state of no power failure and continuous line, and the operation is simple. This series of products has a variety of apertures corresponding to the cable specifications used in the main circuit to meet different use and installation needs. The use of high magnetic permeability magnetic core improves the response time of the transformer to residual current. The unbalanced current monitoring value is better than 5mA, which greatly reduces the false alarm and malfunction caused by the main circuit current magnetic field interference, which provides a sufficient guarantee for the reliability of the equipment.

Installation Precautions

The live wire and the neutral wire must pass through the core hole of the transformer at the same time;

Before the iron core is closed, ensure that the end face of the incision is clean, free of stains and impurities;

Use a torque wrench (electric/pneumatic) when tightening the screws, and set the torque to a reasonable range.
