Product Details

Ohmite 280 Corrib® Series Adjustable Resistors

Ohmite 280 series Corrib® resistors are ideal for applications involving high currents at very low resistance values. These heavy duty resistors are designed to withstand frequent start-stop cycles characteristic of motor starting, dynamic braking and other similar applications. Corrib® resistors are manufactured with corrugated resistive wire. In order 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.
