Rheostats

Rheostats, Open type Single tube : Rheostats are made with a variety of resistance & current carrying capacity so as to satisfy every need. They are wound with heavely oxodised eurika resistance wire upon a porcelene tube dia 44 mm aprox. The tube is carrying upon bakalite ridder and the heavy duty sliding contact is of the phospor bronze with brass rod. 4 mm socket terminals are fitted, allowing for rheostat or potentiometer connection. Total resistance and maximum current capacity is marked on the slidder. Total

Permanent current loading should not exceed 75% of the marked values.Accuracy : The actual resistance of Rheostat shall be +20% -5% of the rated resistance as per our resistance chart. (as per ISI specification no. IS : 9051 S. No. 10.3)
