What is the Difference Between Motor Short Circuit Protection and Overload Protection?

Short circuit when the circuit will produce a large short circuit current and electrical power and make electrical equipment damage. The power needs to be cut off quickly. Common short circuit protection elements are fuses and automatic switches.
The motor allows short-term overload, but long-term overload operation will lead to its winding temperature rise exceeds the allowable value, but also to protect the motor power. A common overload protection element is the thermal relay.
