Oilcooled resistor starters – GINO AG – Elektrotechnische ...
Oil cooled starters are stepped resistance starters with 3PR3 cast iron resistors in a tank filled with mineral based insulating oil. GINO AG acquired the 3PR3 series from Siemens in the year of 2000. The oilcooled starters store the heat dissipated during the starting process and slowly release it to the atmosphere via the tank surface.
