280 Series

Corrib^®Fixed and Adjustable

Vitreous Enamel Power

Corrib^®resistors are ideal for applications involving

high currents at very low resistance values—as low

as 0.1Ω for the 300 Watt unit. 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 are available to accommodate up

to 1500 watts.

Corribs^®are manufactured with corrugated resis-

tive wire. To accelerate cooling, the wire is securely

fused to the ceramic core by the protective vitreous

enamel coating to improve durability. Corrib resis-

tors are hollow-core units which can be securely

fastened to chassis surfaces with thru bolts and

brackets.
