These large, heavy-duty resistors are designed to withstand frequent start-stop cycles characteristic of motor starting, dynamic braking and other similar applications. Special order units ordering infO are available to accommodate up to 1500 watts. ® are manufactured with corrugated resistive Coating Corribs Blank = Vitreous wire. To accelerate cooling, the wire is securely fused to C = Centohm RoHS Compliant S = Silicone the ceramic core by the protective vitreous enamel coating to improve durability.
