Vertically Arranged, Open Type, Two Speed Starters
Vertically arranged starters are used where width limitations prevent the use of the conventional
horizontally arranged device. Such starters may be used to advantage in threaded NEMA Type 7
explosion-proof enclosures, and in multi-motor panels in which other equipment within the enclosure
used limits the available width.
These starters have all the features of the standard horizontally arranged devices, but the two
contactors are in a vertical arrangement. These starters are offered in open type construction only.
Thermal Units
Thermal units should be ordered separately. For selection of thermal units, refer to the Catalog Thermal
Unit Selection Index, Digest or Bulletin SM-416, entitled “Application and Selection of Overload Relays.”
Do not use horsepower rating(s) for thermal unit selection. All three phase two speed magnetic starters
require six (6) thermal units, three per speed. Use nameplate FLC’s (Full Load Currents) from motor
nameplate.
