The Soft-Starter SSW-03 Plus is fitted with a Thermal
Protection. This protection is very efficient for the motor
protection. All Soft-Starter SSW-03 Plus models are fitted
with this protection and always it is activated, error E04
is displayed and the motor is switched off.
This thermal protection has curves that simulate the motor
heating and cooling. The calculation is performed
through a sophisticated software that estimates the motor
temperature by means of the current that is supplied
to the motor.
The actuation curves of the motor Thermal Protection
are according to IEC 60947-4-2 standard.
The motor heating and cooling curves are based on long
experience of the company with its motors. These curves
adopt a standard three-phase motor with IP55 degree of
protection. These curves also consider if the motor is
cooled during operation or not.
