IMPORTANT
This is a generic procedure for replacing existing mercury
switches with microswitches. It pertains to all electronically
operated reclosers from Eaton equipped with such
switches. However, some models of reclosers may have
small parts used only on that particular design. Also, some
reclosers may employ various shim washers to compensate
for tolerance variation. If such parts are present, make note
of them and be sure to reinstall them before returning the
recloser to service.
