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.
