Thermal capacity, also called “maximum locked rotor time” or
“maximum DOL start time”, describes the maximum time a motor
can run at locked rotor current from cold. This information is usually
available from the motor datasheet.
The MCD202 and MCD3000 overload protection can be set to match
the motors thermal capability using the motors locked rotor time
(cold).
