A new and different contact block is needed in the lighting contactor when
the number of poles is changed. A leaf spring must be used on 2–...6–pole
(without a bottom contact block). Two actuators are used on all
configurations. When changing poles, also change catalog number on
nameplate.
Recommended Tools Screwdriver and scriber (to change nameplate catalog number)
