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 termils (Bakelite) are provided – one at each end of the wound resistance wire and third one on one of the supporting legs and connected to the slider arrangement, ebling the use of rheostat as variable resistor or potential divider. Designed for continuous use without overheating. Total resistance in O and current carrying capacities are marked on each rheostat. Pipe diameter approx. 43mm. Available in range Length (mm) 200 Current (A) 5.6A Resistance (Ohm) 10
