Thermal overload relays are installed in the main circuit when electromechanical protection is adequate. To accomplish this, thermal overload relays contain a normally closed (nc) relay. Overload relays are designed to imitate (on a much smaller scale) the heating patterns of the electric motor it is installed in, and interrupt the current though there are different types of overload relays, the most common type is the bimetallic thermal overload relay. A thermal overload relay is an electrical protection device designed to disconnect a machine, appliance, or installation from its power supply should damage or overload occur. The thermal overload relay can make up a compact starting solution together with contactors. Overload will also equate to overcurrent if the supply voltage is essentially constant (whatever the equipment).
Since a thermal overload relay will not trip in case of a short circuit, additional fuses are necessary for short circuit protection. The thermal overload relay is then heated by the secondary current of the current transformer. 5.0 out of 5 stars 1. Thermal overload is widely used for. It is designed to operate under 6 to 7 times more than the full load current.
