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.
