Overload relays are required in a number of applications to prevent damaging conditions from arising. Nearly magnetic equipments are equipped with an overload device to protect the motor from excessive current. Two types of overload relays are used in magnetic starters and these are either magnetic or thermal in operation. Magnetic overload relays react only to excess current and are not affected by temperature. Thermal overload relay rely on the rising of the temperatures caused by the overload current to trip the overload mechanism.
