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.
