Ohmite E300K3R1E Vitreous Enamel Power Resistor

The OHMITE E300K3R1E is a heavy-duty vitreous enamel power resistor within the 280 Series, engineered for demanding applications requiring high current capacity and low ohmic values. Its tubular ceramic core, ribbed construction for rapid cooling, and tinned lug terminals with a hole ensure durability and efficient heat dissipation. Commonly used in motor starting, dynamic braking, and other applications involving frequent start-stop cycles, this resistor is designed to withstand these conditions. Available with adjustable lug options and a wide range of resistance values, the E300K3R1E provides a reliable solution for industrial power management.
