Product description

TR-A series open and close current transxformer,180 degrees open and close freely, indoor use. It can be quickly installed and disassembled in the state of no power failure and continuous line and the operation is simple ,Through the principle of electromagnetic induction ,the measured source is isolated from personnel and equipment ,effectively ensuring the safety of personnel and property. This series of products has a variety of apertures and specifications to meet different use and installation needs.

Product characteristics

The buckle structure is fixed and the stability is good;

According to the cable specifications used in the main circuit, there are various core hole diameters corresponding to it ;

Wide quantity limit and strong anti-saturation ability .Rated primary current range :1~1000A,rated secondary current range :0~5 A, current transformation ratio range can reach 100:1~10000:1;

Provide a variety of combined output methods: when outputting ampere-level current, you can use PVC sheathed wire terminals alone ,output Ma-level current, you can choose three-phrase integrated collection terminals and choose a variety of signal interfaces.

Adopt high magnetic permeability core, good linearity and high sensitively .

Application

Rural power grid reconstruction project, online environmental monitoring ,smart fire-fighting power consumption, low-voltage power distribution system, smart power consumption system, electricity measurement ,power quality analysis and electrical equipment signal collection ,lighting equipment such as power installations, small current grounding systems, etc.

Installation precautions

Before the silicon steel core is closed ,ensure that the end face of the incision is clean ,free of stains and impurities;It must be treated with anti-rust agent;

It is recommended to use a special pry bar/pry tool to open it. Do not break the buckle with excessive force.
