Product Overview

The C300K2R5E is a Power Resistor with vitreous enamel coated tubular ceramic core and adjustable lug. This fixed resistor features tinned lug with hole. The Corrib® resistor is ideal for applications involving high currents at very low resistance values. This large, heavy-duty resistor is designed to withstand frequent start-stop cycles characteristic of motor starting, dynamic braking and other similar applications. The Corrib® is 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. This resistor is a hollow-core unit which can be securely fastened to chassis surfaces with through bolts and brackets. This resistor is designed for equipment requiring low resistance loads at low ohmic values and high current capacity.
  • Ribbed construction aids in rapid cooling
  • 1000VAC Dielectric withstanding voltage
