General
Definite purpose contactors
Definite purpose contactors are ideal for heating, air conditioning, refrigeration, data
processing and food service equipment. New compact single- and 2-pole contactors
are available, as well as full-size 2-, 3- and 4-pole devices.
b Features:
v compact design,
v industry standard mounting,
v double break contacts,
v low coil VA,
v straight-through wiring,
v low cost,
v open contact constructions for easier contact inspection,
v optional cover over contacts.
They feature quick-connect terminals and binding head screws for easy wiring. Box
lugs are standard on 40 A contactors and larger.
An exclusive DIN track mounting option may reduce installation costs.
Coils can be changed on the Type DPA contactors quickly without a tool.
Auxiliary contact modules snap on either side of the Type DPA contactors.
Contactors with fuse blocks
The DPA fused-type contactor provides an integrally mounted fuse block with fuse
clips electrically connected to the contactor. This factory assembled unit not only
provides space savings but reduces installation cost as well, with only six field
connections for a 3-pole unit and featuring one unit for two functions, i.e., short-circuit
protection for branch circuits and remote or manual power circuit interruption. The
fused contactor thus meets the provisions of the National Electric Code (NEC) Article
424 for overcurrent protection as well as limit controls for fixed electric space heating.
By a unique fuse clip arrangement, these devices can accommodate a variety of
fuses for other electrical or electronic applications. This fused cover accommodates
the Type SC 300 volt fuse, which is UL listed under Type G, as well as the standard
10 mm x 38 mm fuses (1).
Only UL-listed, Class G, K, H or J fuses meet branch circuit requirements when
applied in accordance with NEC Article 240. Supplementary fuses shown may be
used for additional equipment protection as defined in NEC 240-30.
Consult the manufacturer of the selected fuse for proper application.
