Ohmite C300KR50 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 common in motor starting, dynamic braking, and similar applications. The corrugated resistive wire is securely fused to a ceramic core with a protective vitreous enamel coating, enhancing durability. Available with silicone coating for higher wattage models, these resistors offer reliable performance in demanding industrial settings. RoHS compliant options are available.
