Product Details

Introduction

The center through hole current transformer is mainly used in the cable circuit environment.Its structure is simple,small in size,flexible in application,and well fit the cable specification used in the main circuit.The diameter of the through-hole of this series is from 30mm~200mm,the main circuit contains 63A~2000A.This series of product can meet the technical requirements of different precision such as 0.2,0.5,and 1.At the same time,it can meet the stringent requirements of the new national standard for balance characteristics.The unbalanced current output value can also be better than 30mA,10mA,5mA.Even 3mA greatly reduces the false alarm caused by the main circuit current magnetic field interference,which provides sufficient guarantee for the reliable of the equipment.Excellent and advanced production process.To ensure the accuracy level,reliability and other technical requirements,this series of products meet the requirements of GB-14287.2-2005 and GB 14287.2-20140.

Features

1. Center through core structure and the flame retardant epoxy resin are poured and have good stability

2. Using high magnetic nickel steel or nanocrystalline,excellent linearity,high sensitivity.

3. Excellent balance characteristics,and has strong resistance to electromagnetic interference

Usage

Excellent fire monitoring,fire prevention system,smart power system,small current grounding system,electromagnetic relay,computer protection,etc.
