| WHERE
TO USE GE CONTACTOR DS303 & IC2800
The
GE contactor DS303 & IC2800 are used for heavy duty
dc industrial applications such as steel mills, cranes,
material handling, rapid transit as well as generalduty
machine tool, textile machinery and similar applications.
Both GE contactor DS303 & IC2800 have a steel base
insulated from the electrical circuits. They can be mounted
on either metal or insulating panels.
NEMA Size 1-5 are available in various NO and NC pole
combinations. Sizes 6-10 available in NO pole only.
Advanced
design arc chutes (non-asbestos) provide make
or interrupt ratings of up to ten times the contactor
ratings for 600-volt applications and four times the contactor
ratings for 1000-volt applications. The arc is completely
extinguished within the arc chute structure.
Select-contactor
ratings on the basis of both dc current-carrying
capacity and blowout ratings. The blowout rating establishes
the contactor current rating and interrupting rating.
Larger contactors are used because the increased tip gap
provides improved interruption on the lower current application.
The
function of the blowout coil is to move the arc
upward at the same time the contacts are opening, thus
forcing the arc away from the tips and into the arc chute
at a faster rate.
