Where is the overheating protection device located on the Abac Start L20 compressor?

Question

Accepted Answer

The thermal protection device of the Abac Start L20 compressor is located on the electric motor terminal box, easily identifiable by the presence of a small reset button. This safety component operates automatically: in case of motor overheating, it immediately cuts off the electrical power to protect the compressor.

This protection system generally activates when the motor draws excessive current due to prolonged use or overload. To avoid false triggers, strictly adhere to the operating cycle indicated on the motor's nameplate (for example, S3-50, which means 5 minutes of operation and 5 minutes of rest).

If the compressor stops after overheating:

Wait a few minutes to allow the motor to cool down completely
Unplug the compressor from the power supply
Manually press the reset button located on the motor terminal to reset the protection
Plug in and restart normally, ensuring that the pressure switch is in the off position (OFF) before connecting

Prevention: Ensure that the compressor operates in a well-ventilated environment with an ambient temperature between +5°C and +40°C. Avoid repeated overloads and regularly check the oil level, as insufficient lubrication increases motor resistance and may trigger the thermal protection.
