Motor Controller
THE CONTACTORS
The A200 motor controller, when wired as shown in Figures
5 and 6, will operate as a full voltage starter and will give
protection against overload, but not against short-circuit currents,
when wired and provided with overload relay (OLR) heaters as
listed in heater selection tables or when used with any means of
inherent protection activated by motor temperature.
The controller should be protected against short circuits by
providing branch circuit protection not to exceed the maximum
protective device ratings listed in Table I.
This industrial type control is designed to be installed, oper-
ated, and maintained by adequately trained workmen. These
instructions do not cover all details, variations, or combinations of
the equipment, its storage, delivery, installation, check out, safe
operation, or maintenance. Care must be exercised to comply with
local, state, and national regulations, as well as safety practices,
for this class of equipment.
AUXILIARY CONTACTS - TYPE J
A J20 with two normally-open poles is supplied mounted in the
upper left hand corner recess of the contactor. One pole is used
as the holding circuit auxiliary.
