Answer / Abhishek Kumar Paisal

The corner breaker tripping issue in indoor circuit breakers can occur due to the formation of condensation and ice during colder seasons. This moisture can accumulate at the corners, leading to corrosion and an increase in resistance over time. When a heavy load is applied or a fault occurs, this additional resistance can cause the breaker to trip instead of protecting the circuit.
