280 Series
Corrib Fixed and Adjustable
Vitreous Enamel Power Resistors
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
accommodate up to 1500 watts.
Corribsare 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.
FEATURES
Ribbed construction aids in
rapid cooling.
Designed for equipment
requiring low resistance loads
at low ohmic values and high
current capacity.
Especially constructed for
motor starting, dynamic
braking, etc.
SPECIFICATIONS
MATERIAL
Coating: Lead free vitreous
enamel except for extreme low
resistance 35 watt models, and
very large models (1000 watts
and up), which are supplied in
Silicone Ceramic.
Core: Tubular Ceramic.
Terminals: Tinned lug with hole.
Adjustable Lug: Supplied with
adjustable 300 watt models. Part
No. 1974-A or 1974-B.
