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 resis-
tance with lower power capac-
ity is required use our Round
Wire design.
These resistors are con-
structed of a heavy resistance
alloy mounted on ceramic
insulators and supported by
a metal mounting bracket.
Metal parts, except for the
resistance element, are heav-
ily plated to prevent oxidation
at high operating temperatures
and to prevent corrosion. The
mounting bar is slotted on
each end to facilitate installa-
tion. Edgewound units provide
clamp-type terminals, permit-
ting a reliable connection
which can be moved along
the resistive element to obtain
intermediate values.
SPECIFICATIONS
Electrical
Current Rating: Continuous duty
as listed on following page.
Wattage Rating: 700 to 1,000 (up
to 1,600 watts on special order)
Resistance Tolerance: ±10%
standard, ±5% available
Terminals: Clamps, movable
along resistor wire for setting
intermediate resistance values
on Edgewound units (current
must be derated in proportion).
Temperature Coefficient:
±300 ppm/°C for resistors 50
amps and more
±500 ppm/°C for resistors 47
amps or less
Ohmic Values: See chart on fol-
lowing page.
Mounting: Metal mounting bar is
slotted on each end to facilitate
installation.
Short Term Overload: 10x rated
wattage for five seconds

dard resistance values when
ordering.
