Precision tooled parts, computer aided
design and advanced production
techniques, as well as the protection of
the 'E Coat' (cathodic electrocoating) paint
process have resulted in a standard of
excellence unmatched in the industry.
SecoVac is designed, assembled and tested
to meet or exceed applicable IEC, GB and
DL standards. It is suitable for applications
in all major industries including T&D, Oil
& Gas, Automotive, Processing plants,
Iron and Steel mills, Mining, Commercial
buildings, etc.
It provides protection for all types of
applications: coble, overhead lines, motors,
capacitors, transformers, busbar sections,
etc.
Selecting low environmental impact
technologies has become increasingly
important to engineers tasked with
choosing equipment for an application.
With commitment to environment
protection, the solid insulation of epoxy
resin is used for SecoVac series MV
embedded pole vacuum circuit breaker
instead of SF6gas.

stop is provided when the breaker
reaches the service or test/disconnect
positions. Mechanical rejection interlocks
are provided to permit only the insertion
