RARA ULV300N 20 Ω is a non-inductive, metal-clad, wire-wound power resistor in the ULV300N family, optimized for industrial environments. It carries a 300 W rating when mounted on a heatsink (210 W in free air) and a resistance of 20 ohms with a typical tolerance of ±5% (J). The ULV300N is designed for high-energy dissipation in applications such as braking resistors for industrial drives and load banks, and it sits within a non-inductive ULV300 series that covers values from 0.1 Ω up to 1.5 kΩ. Built for rugged use, the unit is aluminum-housed and chassis-mount, offering robust thermal performance and reliable operation in harsh electrical environments.
