The C300K2R0E is a Corrib? Resistor designed to withstand frequent start-stop cycles characteristic of motor starting, dynamic braking and other similar applications. Tubular ceramic core. Corribs? are manufactured with corrugated resistive wire. To accelerate cooling, the wire is securely fused to the ceramic core by the protective vitreous enamel coating to improve durability. Corrib resistors are hollow-core units which can be securely fastened to chassis surfaces with thru bolts and brackets. Designed for equipment requiring low resistance loads at low ohmic values and high current capacity. Power rating of 300W and temperature coefficient of ±400ppm/°C.
