Overload relays are of ________ type.

Question

Overload relays are of ________  type.

RRB Paper · Accepted Answer

Overload relays can be of solid-state, thermal or electromagnetic type depending on their design and application. Solid-state overload relays use electronic components such as transistors, thyristors or microprocessors to detect and respond to overloads in electrical circuits. Thermal overload relays use bimetallic strips that are heated by the current flowing through them. The heat causes the strips to bend, activating the overload relay and tripping the circuit. Electromagnetic overload relays use a magnetic coil that generates a magnetic field proportional to the current flowing through it. When the current exceeds a set limit, the magnetic field activates the overload relay and interrupts the circuit.
