GCMS-3 series are aluminium body with plastic insulation and lug terminals. These are electrolytic AC motor start
The body of these capacitors is insulated with a PVC heat shrink sleeve which retains the shape under high temperatures.
The top of the capacitor is sealed with a special rubber bonded bakelite disk. There is a thin layer of rubber on the disk’s
round hole which acts as a vent hole & passes out gas from the capacitors in case of excess pressure thus acting as a
safety mechanism. They are easy to install with a motor frame.
