The Neutral Earth Switch is designed for the
used in the rural distribution environment. It
is an established, robust and reliable design
which has been fully type tested to
international standards (IEC265 and IEC694).
The Double Side Break (DSB) is installed for
sectionalizing and isolating various circuits
and equipment in substation system. The
Double Break operation is electrically
superior to the Single Break because two
breaks in series per phase are achieved. The
Double Break Isolator and the manual
operating mechanism drives are fully
universal, therefore suitable for either
horizontal or vertical mounting.
