A <strong>comprehensive</strong> <strong>range</strong> <strong>of</strong> <strong>Euroload</strong> <strong>Switch</strong> <strong>Disconnector</strong> (Load Break <strong>Switch</strong>es) have been designed and developed<br />
indegenously to meet various needs <strong>of</strong> distribution circuits. The switches are compact and suitable for AC-23A duty.<br />

Construction<br />
The switching mechanism is quick make, quick break type<br />
independent <strong>of</strong> the speed <strong>of</strong> the operation. There are four breaks per pole<br />
thereby resulting into faster quenching <strong>of</strong> arc. The load and line can be<br />
connected on either side by virtue <strong>of</strong> isolation on both the sides. The entire<br />
<br />
<br />
<br />
Contact Mechanism<br />
The contact mechanism is knife blade type with self cleaning<br />
<br />
have separate main and arcing contacts. The moving contact<br />
<br />
assembly rests on the spring loaded steel balls fitted in moving carrier in<br />
ment<br />
during making and breaking.<br />
ment<br />
<strong>of</strong> the moving contact assembly. The contact is first made with the<br />
arcing contact and thereafter with the main contact. During breaking, the arc<br />
formation is across the arcing contacts thereby protecting the main contacts<br />
which results into enhanced life <strong>of</strong> the switch. The arc is effectively quenched<br />
<br />
<br />
mode without any effect on the performance.<br />
Operating Mechanism<br />
<br />
operated handle which drives the spring assisted toggle<br />
mechanism, inturn operating the switch.<br />
