Ohmite C300K1R0 Vitreous Enamel Power Resistor
OHMITE's 280 Series Corrib[®] resistors are specifically engineered for applications requiring high currents at very low resistance values. These heavy-duty resistors are built to withstand frequent start-stop cycles commonly found in motor starting, dynamic braking, and similar industrial processes. The corrugated resistive wire is securely fused to a ceramic core with a protective vitreous enamel coating, enhancing durability and promoting rapid cooling. Available in various configurations and with optional silicone coating for higher wattage applications, the C300K1R0 offers a reliable solution for demanding power management needs.
