ESAW (EEC-10685) Resistors Sliding Contact Rheostat, Open Type, Single Tube
For use as series resistors or potentiometers. Comprises of eureka wire wound on a porcelain tube, supported at both ends on moulded plastic legs. Open type
slide wire type with a variety of resistance and current carrying capacity. Copper-nickel alloy wire is oxidized to provide the desired insulation. Phosphorus
bronze contact provided on metal chrome plated slider-rod to give rapid and smooth adjustment. Three 4mm socket terminals are provided — one at each end of
the wound resistance wire and the third one on one of the supporting legs and connected to the slider arrangement, enabling the use of rheostat as a variable resistor
or potential divider. Designed for continuous use without overheating. The total resistance in QO and current carrying capacities are marked on each rheostat. Pipe
diameter approx. 43mm.
