These resistors are
designed primarily to withstand heavy overload surges up to max 7 times
their rated wattage for 10 to 15 seconds (max). This characteristic makes
them most suitable for controlling motors requiring
high dissipation, low
resistance values and high current capacity.

fitted mounting brackets they are
suitable for use in situations where shock and high
frequency
vibration forces are to be encountered.

Adjustable
resistors for applications requiring settings at different resistance
values. These wire wound resistors are equipped with an adjustable lug,
making them ideal for adjusting circuits, obtaining odd resistance values
and setting equipment to meet various line voltages.

Type resistors feature a hollow core to permit secure fastening with
spring-type clips or thru bolts with washers. They also offer the
durability of lead free vitreous enamel coating and all-welded construction.

"thin" stackable 250 Type resistors. These oval-shaped
ceramic-core resistors feature a low profile to permit installation in
spaces with minimal height. They are also equipped with integral mounting
brackets so they can be fastened to a chassis and stacked in locations with
limited surface area

Select 270 Type fixed resistors for
applications requiring wattage ratings from 12 to 1000 watts.
The 270 Type resistors are equipped with lug
terminals suitable for soldering or sturdy bolt connection. When secure
mounting is required, the hollow core of these resistors permit fastening
with spring-type brackets, thru bolts or thru bolts with slotted-steel
brackets construction.

Corrib® resistors are ideal for
applications involving high currents at very low resistance values-as low
as 0.1 ohm for the 300 Watt units. These large, heavy-duty resistors are
designed to withstand frequent start-stop cycles characteristic of motor
starting, dynamic braking and other similar applications. Special order
units are available to accommodate up to 1500 watts.
Corribs®are manufactured with
corrugated resistive wire. To accelerate cooling, the wire is securely
fused to the ceramic core by the protective vitreous enamel coating to
improve durability Corrib resistors are hollow-core units which can be
securely fastened to chassis surfaces with thru bolts and brackets. Also available in low-cost Centohm

These high current round edgewound
resistors handle a variety of applications including dynamic braking, load
banks, motor starting, and plugging. They are available in a variety of ohm
and current ratings common to transit use.
A sturdy welded steel frame supports the
refractory insulators. The frame is finished with a zinc chromate
conversion for corrosion resistance. The ceramic insulators separate turns
of the resistance elements from each other and the frame. The resistance
element is a stainless steel strip, used for its corrosion resistance,
negligible temperature coefficient, and Ohms per foot vs. current carrying
capacity. The resistance element is created by edge-winding a stainless
strip into a continuous coil of the proper length. Zinc plated terminals
welded to the resistance element complete the assembly.

Designed in both Edgewound
and Round Wire formats, these rugged resistors can handle 700 to 1000 Watts
of power. Specify our edgewound design for very
low resistance and high power capacity. When higher resistance with lower
power capacity is required use our round wire
design.
Constructed of a heavy resistance alloy
mounted on ceramic insulators and supported by a metal mounting bracket.
Metal parts, except for the resistance element, are heavily plated to
prevent oxidation at high operating temperatures and to prevent corrosion.
The mounting bar is slotted on each end to facilitate installation. Edgewound units provide clamp-type terminals,
permitting a reliable connection which can be moved along the resistive
element to obtain intermediate values.
