Edison™ Single-Phase Vacuum Capacitor Switch
Ratings and specifications
Check switch ratings before installation
The Edison capacitor switch must be applied within its
specified ratings. Check data plate ratings and compare with
the system characteristics at the point of application prior to
installation. Table 1 list the ratings and specifications for the
Edison capacitor switch.

otee:
The durability of the Edison capacitor switch was demonstrated by completing a minimum of 50,000 mechanical
operations after performing the Mechanical Life Test in accordance with IEEE Std C37 .66™-2005 standard. One
operation is defined as one close and one open operation.
