Sliding Rheostats,Adjustable resistor Three-tubes, 6-50A，1.3-70Ω

 Description of  Sliding Rheostats：This series adjustable resistors are constructed of 3 wirewound tubes can be powered with about 65% of the corresponding nominal load of the fixed types with corrugated wire for extra high demands on surge or pulse load. They are wirewound enameled or cement coated resistors with an open area along the resistors where the resistor wire is un-coated..
