due to the extension of loads they are using the relays for protection.........
No there not same
A relay cannot be used to power a motor. It can be used to control the motor by wiring the motor circuit in series with the relay contacts.
over current protection relay
It is the one type of coil in the electrical motor starters. It is used to release the switch, i.e. turns off the motor, when heavy load is connected to the motor. It is used for the protection purpose.
A device with an overload protection used to control a motor is an Overload Relay.
An MP3000 Motor Protection Relay is designed to protect motors against abnormal operating conditions. The MP3000 is considered a very advanced system and offers many different features such as overload protection, easy unit configuration, and an armed/disarmed feature.

Where is the blower motor relay at.
A relay cannot be used to power a motor. It can be used to control the motor by wiring the motor circuit in series with the relay contacts.
when the cable of a motor shorted then differetial relay act
one way is to use RTD sensor put inside the motor windings. The RTD sensor is connected to an electronic thermal overload relay. This type of relay can provide running temperature of the motor, on the electronic thermal over load relay display panel. RTD sensor is a wire wound resistor that changes resistance depending on the temperature
== == Most likely, the condenser fan motor is going bad. Most motors of this type have a thermal protection relay that will cut the power if the motor gets too hot.
over current protection relay
The wiper motor relay is in the box, built on the wiper motor.
LBB is local breaker protection
