Frequently Asked Questions (FAQ) about Circuit Breakers

Q1: How do I choose the right circuit breaker for my application?
A1: Start by determining the load current and voltage of your system. Then consider the environment (residential, commercial, or industrial) and select the correct type (MCB, MCCB, RCCB). For example, an MCB is ideal for household circuits under 100A, while MCCBs suit industrial setups with higher currents and breaking capacities.

Q2: What causes a circuit breaker to trip frequently?
A2: Frequent tripping can be due to overloads, short circuits, or ground faults. Check if too many appliances are connected to one circuit or if any wiring is damaged. Also, ensure the breaker's current rating is appropriate for the load.

Q3: Can a circuit breaker go bad and still look normal?
A3: Yes. Visually, a breaker may appear intact, but its internal trip mechanism might fail. If you experience issues like failure to trip, irregular power supply, or burning smell, it's best to replace the unit. Periodic testing is essential to verify operational integrity.
