PHYSICAL CONFIGURATION

D-Dimensions given are indicative and could exceed tolerances given depending on resistance value being wound.

Resistor types suffixed with ‘A’ are compatible with Amp 187 connectors from 40 watt to 50 watt size and are compatible with

Amp 250 connectors from 60 watt to 600 watt size. Resistor types suffixed with ‘B’ have large center holes in the lugs-refer

Øld, to facilitate attaching cables to them by using nut & bolt or soldering after threading the wires through them.

TYPICAL APPLICATIONS

In RSR series, a corrugated alloy tape is wound edgewise or flat onto a ceramic tube which is coated with a silicone cement which is

compatible with UL standards.

This ribbed construction puts both sides of the resistive element in contact with air thus creating a convention area four times greater

than that obtained with normal wire wound resistors.

These resistors are designed primarily to withstand heavy overload surges upto max 7 times their rated wattage for 10 to 15 seconds

(max). This characteristic makes them most suitable for controlling motors requiring high dissipation, low resistance values and high

current capacity.
