Engineered Medium Voltage Starter Options
Surge / Lightning Arrestors
The surge or lightning arrestors are available in two options. If the unit is required to be UL approved
the surge arrestors must be installed on the top of the unit (components are shipped loose and must be
installed by customer). This will add eighteen inches to the height of the enclosure. For units not requir-
ing UL approval the arrestors may be installed inside the enclosure. This requires the enclosure width to
increase to the next standard size. Includes the hardware necessary to mount and wire the arrestors and
the increased size of the enclosure where required.
