RHEOSTATS
Wire wound on Enamelled Iron pipe having dia 5.6cm. Supports are made of Aluminium. Consists of a layer of superior quality oxidized eureka wire wound on an insulating heat-resistant porcelain tube which is supported at both ends by cast iron, enamel painted, stain-finish feet. A bakelite sliding contact with laminated phosphor-bronze strips is provided. Three 4 mm socket terminals with captive heads are provided. Each rheostat was tested for current carrying capacity. A special feature of our rheostats is that they are manufactured for continuous use without overheating. Tolerance in nominal marked value of resistance is- 5% and + 20%. Given below are a few representative ranges only.
