WLrh series

Heliohm Wirewound

Dimensions

or D ering information

The WLRH is a tough, versatile resistor appropriate

for the following applications: motor starting and

speed control, neutral grounding, lighting ballasts,

and A.C. compressor buffers. This resistor can also

be used in heating applications. 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 cor-

rosion resistant stainless steel.

Other mounting options are available; contact us

about your specific requirements.

Inquires are welcome regarding special resistance

values, frames, screened enclosures, heat shields

and packages.
