DPM 750V Contactor
Product Description
The DPM 750 Vdc Definite
Purpose Contactor has been
designed to meet severe
environmental and vibration
conditions found in your
worst applications. The
contactor is of unit
construction, assembled
on a molded insulated
base, providing maximum
performance in minimum
space.
Application Description
This rugged device was
designed for applications
such as railway equipment,
offshore drilling, mining, off-
road vehicles, marine, and
so on.
Features
●
Power circuit insulating
barriers are molded from
glass-polyester materials
having high arc and track
resisting qualities
●
The DPM is designed to
mount directly on a
channel or angle frame, but
may be adapted for
mounting on a flat metal or
insulated panel
●
Available with or without
an overcurrent latching
mechanism to prevent
opening under heavy
overload currents. When
the line current returns to
normal, the overcurrent
latch disengages
Benefits
●
Saves panel space by
locating the arc chute vents
on the front of the unit.
This eliminates the need
for arcing clearance above
the contactor
●
All vital parts are
removable from the front
without having to
disconnect line or load
connections, allowing for
easy maintenance
●
Safety is a must. The
mechanical interlock
prevents the contactor
from closing when the arc
box has been removed or
when it is not installed
properly
