FAQs

What is the meaning of 16A?

16A refers to the maximum current the MCB is designed to carry continuously without tripping.

What does Type B mean?

Type B indicates the trip curve, specifying how quickly the MCB trips in response to overcurrents. Type B MCBs are typically used for domestic and light commercial applications.

Where should I install the MCB?

The MCB should be installed in a distribution board or consumer unit, protecting the individual circuits.

Can I use this MCB for a three-phase circuit?

No, this is a single-pole MCB and is not suitable for three-phase applications.

What is the breaking capacity?

The breaking capacity (6kA in this case) indicates the maximum fault current the MCB can safely interrupt.

How often should I test the MCB?

It's recommended to test MCBs periodically, following local regulations and guidelines.

Who should install the MCB?

Installation should only be performed by a qualified electrician to ensure safety and compliance with regulations.

Troubleshooting

MCB trips frequently.

Check for overloaded circuits, short circuits, or faulty appliances. Replace the MCB if it continues to trip with normal load.

MCB fails to trip during a fault.

Immediately replace the MCB. Contact a qualified electrician to inspect the circuit and wiring.

Difficulty in resetting the MCB.

Ensure the fault has been cleared. If the MCB still won't reset, it may be faulty and require replacement.
