WLRH Series

Heliohm Wirewound

The WLRH is a tough, versa-

tile resistor appropriate for the

following applications: motor

starting and speed control,

neutral grounding, lighting bal-

lasts, and A.C. compressor

buffers. This resistor can also

be used in heating applica-

tions. Choose from 45 models

ranging from 0.25 to 250

Ohms to best fit your specific

requirements.

Resistors feature nickel-

copper, nickel-chrome or

stainless steel wire wound in a

double helix around the center

core, depending on size and

model. All have ceramic cores

with a spiral groove to grip the

coiled wire. The 90° flat bus

style terminals are corrosion

resistant stainless steel.

Other mounting options are

available; contact us about

your specific requirements.
