Jindal Steel Plant Interview Questions and Answers

Q1. What is the working principle of an overload relay?
Ans. 
An overload relay works by monitoring the current flowing through a motor and tripping when the current exceeds a set limit.
• Monitors the current flowing through a motor

• Trips and interrupts power when current exceeds a set limit

• Protects the motor from damage due to overloading

• Can be reset manually after tripping
