An over laod protection device is a thermal device used to protect and disconnect the main circuit and the motor and in some cases disconnect the control circuit,if for any reasons the motor exceeds the set trip current
over load disconnect motor from supply in case high current more than rated current due to larger torque of motor .
Overload uses for protection against over current which damaged motors
to prevent motor from getting overloaded i.e. motor should not run beyond FLA full load ampere
protection from the over current which wil burned the motor
To Protect Motors from Overloading, High Ampere that causes Burning.
Protection of the motor windings from burning or it's insulator from being thermally stressed.
In the most general sense, the load is the thing that is connect to the output of an electrical circuit. The load can basically be anything. For example, it can be a resistor, or a capacitor or an inductor, or a transistor, or a motor, or an air conditioner etc.it also used to vary the output voltage,current,power
overload relays are used to protect motors, if motors take high current then its capacity, either due to mechanical (Bearing or Pump etc) or electrical winding problem, the overload trips and protect motor from any kind of damage.
Over load rellays are used for the protection of moter. These rellays sense the overload current and hence prevent from over heating of motor winding
Overload relays use for protection of motors
