Description
The ABB TF42-13 Overload Relay is used to protect HVAC system motors from overheating and overloading. The relay has a rating of 10-13 amps, which makes it possible to detect excessive current and protect the motor from damage. It operates by cutting off the circuit if the current rises to a certain value and therefore protecting the motor. They are most widely used in HVAC systems where it provides a safety measure for protecting compressors, fans and all other components that have motors. Its precise functioning and short cycle time increase the dependability of the system, minimize the time that the HVAC equipment, and extend the useful life of the equipment.
