Introduction

Arrester disconnector is a device for disconnecting an arrester from the system in the event of arrester failure,

to prevent a persistent fault on the system and to give visible indication of the failed arrester,

The thermal explode disconector, meets as per IEC60099-4.Thermal explode type disconnector only operates

if power frequency fault current flows through the device during a failure. It will not operate from surge current.

Main parameters:
● Long duration current impulse 2000μs: 600A
● High current impulse 4/10μs:  100 kA
● Current-time characteristic

Current Level Power frequency current (A rms)
