Product Structure
SecoVac 3.3kV-27kV Breaker Features
Introduction and Type Description
Up to 17.5kV
Primary disconnect
Breaker mechanism
The primary disconnect cycloid (tulip)
contact set is rugged and easy-to-inspect.
Designed for optimum contact area,
it is manufactured from silver-plated
copper and tested for continuous and
short-circuit current ratings. The tulip
cluster design expands easily, providing
$
contact designs, and delivering proper
contact integrity throughout the life of the
equipment.
All the mechanical parts of the mechanism
are integrated into individual opening
and closing modules. The modules are
universal to SecoVac embedded pole
vacuum circuit breaker series, regardless
of rating. The module design assures no
mechanical adjustment is required after
" = !
lead-times and reduces operational and
maintenance costs.
