1. Learning outcome 2 Motor protection

2. Over temperature protection If the temperature of the insulation is exceeded, it starts to degrade and will eventually fail.

3. The most common and effective protection is thermal overload devices.

4. Primary resistance starter TOL device

5. L/O 2.4

6. L/O 2.4

7. L/O 2.4

8. Typical TOL with adjustable settings. Adjustable electronic protection device with overload, phase failure and asymmetry protection.

9. Insulation damage due to overload in 2 phases.

10. Rotor damage due to locked rotor condition.
