Ohmite E300KR10E Vitreous Enamel Power Resistor
Ohmite's 280 Series Corrib[®] fixed and adjustable vitreous enamel power resistors are engineered for applications requiring high currents at very low resistance values. These heavy-duty resistors are designed to withstand frequent start-stop cycles commonly found in motor starting, dynamic braking, and similar industrial processes. Constructed with corrugated resistive wire securely fused to a ceramic core with a protective vitreous enamel coating, Corrib resistors offer enhanced durability and efficient cooling. Available in various configurations and with optional silicone coating for higher wattage applications, the E300KR10E provides a reliable solution for demanding power management needs.
