Question

Describe the importance of an overload protector with the help of a diagram.

Hint:

Overload protector = automatic safety switch for motors!

Answer 1

An overload protector is a safety device used in electrical appliances like refrigerators, air conditioners, and compressors.
Its main purpose is to protect the motor or compressor from damage due to excessive current or overheating.
When the current exceeds a safe limit or the motor temperature rises too high, the overload protector automatically disconnects the electrical supply.
This prevents the winding insulation from burning and extends the life of the equipment.
Once the temperature or current returns to normal, the protector resets itself or can be manually reset.
Overload protectors are simple, cost-effective, and essential for safe operation.
