The 40AA, 41AA, and 42AA series
electronic motor protection modules
combine high performance and function
consolidation in order to provide reliable,
cost effective protection for your motor
needs. Used with Positive Temperature
Coefficient (PTC) sensors the
40/41/42AA modules protect against
locked rotor conditions, running overload
and high ambient temperature. The
innovative design offers additional
functions as well, such as minimum off
time delay, low voltage cutout and
bearing temperature protection. Also the
device is very safe and easy to calibrate
for voltage (no jumper is required).
Thermal protection is achieved by
monitoring the temperature of the motor
windings with PTC sensors. These
sensors can be the Klixon BA series or
any other compatible PTC sensor rated
Mark A or B. If the windings exceed the
rated trip temperature the sensor
undergoes a rapid change in resistance
relative to the change in temperature. As
a result of this change, the 40/41/42AA
modules' internal relays de-energize the
control coil of the external line break
contactor.
As the motor cools and acceptable motor
winding temperatures have been restored
the sensor resistance decreases to the
reset level. At this point the module will
reset itself automatically unless it was
set up for manual reset. In this case the
user is required to remove power from
the system for a minimum of 5 seconds.
The 40/41/42AA series modules are
Product Overview
ideal for many applications in the
HVAC/R industry as well as for industrial
systems. Some applications include
global commercial rooftop A/C, global
chiller applications, industrial pumps,
material handlers, elevators, escalators,
air compressors and industrial systems.
