1 / 2 page  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.
