Arcol Ohmite, 20Ω 696W Wire Wound Panel Mount Resistor PFR5K20R0E ±10%

Ohmite Powr-Rib® series Edgewound and Round Wire rugged resistors, designed to handle 700 to 1000 Watts of power. Edgewound resistors are designed for very low resistance and high power capacity, and the Round Wire resistors are used when higher resistance with lower power capacity is required.
These resistors are 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.
