Motor protection devices working

Question

Accepted Answer

Motor protection devices are used to prevent damage to motors due to overloading, overheating, and other faults.

Motor protection devices include thermal overload relays, circuit breakers, and fuses.
Thermal overload relays protect against overheating by monitoring the motor's temperature and tripping the circuit if it exceeds a certain level.
Circuit breakers protect against overloading by interrupting the circuit if the current exceeds a certain level.
Fuses protect against short circuits by melting and breaking the circuit if the current exceeds a certain level.
Other motor protection devices include voltage monitors, phase monitors, and ground fault detectors.

Accepted Answer

It is an instantaneous action device __ magnetic or electronic...capable of detecting an cutting any current greater than starting current of the motor.
