Protection and Features:
•
•
Electronic thermal motor protection against overload.
Temperature monitoring of the heatsink ensures that the frequency converter trips if the
temperature reaches a predefined level. An overload temperature cannot be reset until
the temperature of the heatsink is below the values stated in the tables on the following
