Size 3 or 4 Reversing Motor Controller

THE CONTROLLER

An A210 or A250 motor controller, when wired as shown in the 
appropriate connection diagram 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 II.

This industrial type control is designed to be installed, operated, 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 - L56 
(RATED B600)

Two L56’s, each with one normally open pole 
and one normally closed pole, are supplied as 
the holding circuit auxiliary and electrical interlock 
between the two coil circuits. A maximum of three 
L56 auxiliary units can be installed in the recesses 
of each contactor. These may be mounted with 
the terminals in line with the power poles or may 
be mounted with the terminals in a right angle 
relationship to the power poles. They mount by 
means of a spring clip which snaps into locations 
provided in the motor controller unit. To remove the 
L56 disengage the top spring clip, by pressing on 
the extended tab, and withdraw the unit.
