Abstract: This article introduces the application of Acrel ASJ residual current action relay application for 1000A main breaker.

1.Project Overview

This company is located in Panama and is the software service company in Panama. Mainly used  ACREL ASJ20-LD1A residual current relay and leakage current transformer accordingly.

2.ASJ Series Residual current relay Introduction

ASJ Series of action relay of after-current, low-voltage circuit break or low-voltage

 contactor can be made up for combined after-current production device, which is mainly

applied for the TT and TN system distributing circuit with the alternating current 50Hz, the rated voltage 400V or below.ASJ Series of action relay of after-current is applied in the earth fault protection for the electric circuit, so as to prevent the equipment damage and the fire accident of electric equipment caused by the ground fault current, moreover, it also can provide indirect contact protection against the electric shock risk.
