① Wood products used in the packaging are either hardwood or certified
by the wood supplier as being “heat treated (kiln dried) to a core
temperature of 133°F (56° Celsius) for a minimum of 30 minutes.”
② When catalog number suffix “-M1” or “-M2” is specified, cable-
termination options (catalog number suffixes “-U2” and “-U3”) cannot
be accommodated. In addition, when catalog number suffixes “-M1”
and “-M2” are both specified, only one cable guide is pro vided at each
switch terminal.
③ These devices extend below the base of the unit. Provide a cable pit
or specify a base spacer that provides a 12-inch (305 mm) or greater
increase in cable-termination height.
④ Surge arresters are base-mounted only (without isolators).
● Not applicable to 25-kV models.
■ Not applicable to 14.4-kV models.
▲ A supplemental label is provided for catalog number suffixes “-N11”
and “-N12” indicating the voltage rating of the surge arresters furnished.
