Catalog excerpts

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 corrosion resistant stainless steel. Other mounting options are available; contact us about your specific requirements. OPTIONS Inquires are welcome regarding special resistance values, frames, screened enclosures, heat shields and packages. CHARACTERISTICS Current Rating 1.0 - 32.0 Amps continuous Wattage Rating Wattages can be calculated using I2R from the data in the standard resistance value table. These are maximums for continuous duty allowing a 375°C temperature rise. Working Voltage Standard is 600 volts maximum to ground Resistance Tolerance ±10% Ohmic Values Ohmic values listed in the table are at 25°C ±10% Mounting Resistors can be mounted in various options NFORMATION Standard Resistance Values Number Ohms Rating Number Ohms Rating Number Ohms Rating Part Number Cont.
