Corrib^®resistors are ideal for

applications involving high

currents at very low resistance

values—as low as 0.1 ohm for the

300 Watt units. 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

280 Series

Co rrib ^®Fix e d a n d Ad ju s t a b le

Vit re o u s En a m e l P o w e r Re s is t o rs

accommodate up to 1500 watts.

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.
