FAQs

What does a Type B curve mean?

A Type B curve means the MCB is designed to trip at 3 to 5 times its rated current, suitable for general domestic and light commercial applications.

What is the breaking capacity?

The breaking capacity is 6kA, which means it can safely interrupt fault currents up to 6,000 Amperes.

Can I replace the MCB myself?

Replacing an MCB requires electrical knowledge. It is recommended to have a qualified electrician perform the replacement to ensure safety and compliance.

What is the function of an MCB?

An MCB (Miniature Circuit Breaker) protects electrical circuits from overcurrents and short circuits, preventing damage to wiring and appliances and reducing the risk of fire.

How do I know if the MCB is faulty?

If the MCB trips frequently without an apparent cause, fails to switch on, or shows visible signs of damage, it may be faulty. Consult with a qualified electrician to inspect and replace it if necessary.

What does SP mean?

SP means Single Pole, indicating that the MCB protects only one live conductor.

Troubleshooting

MCB trips frequently.

Check the connected devices for faults or overloads. Consider reducing the load or replacing the MCB with a higher rated one if appropriate (consult a qualified electrician).

MCB does not switch on.

Check the connections, the MCB itself for damage, and the circuit for any short circuits. If the MCB is faulty, replace it.
