FAQs

What does 'Type B curve' mean?

A Type B curve indicates the circuit breaker's tripping characteristics. It is suitable for general domestic and commercial applications and will trip relatively quickly under fault conditions.

What is the breaking capacity of this circuit breaker?

The breaking capacity is 6kA (kiloamperes), indicating the maximum fault current it can safely interrupt.

Can I use this circuit breaker for outdoor applications?

The circuit breaker is not designed for outdoor use unless installed within a suitable weatherproof enclosure.

What happens if the circuit breaker trips?

When the circuit breaker trips, it cuts off the power to the protected circuit. You can reset it by switching the lever to the 'off' position and then back to the 'on' position, after resolving the fault.

How often should I replace this circuit breaker?

A well-maintained circuit breaker should last for many years. However, it is advisable to replace it if it frequently trips or if there is any visible damage.

Where can I find the specifications for the Wylex NHXB10?

Detailed specifications can be found on the Wylex website or in the product documentation.

Troubleshooting

Check the load on the circuit. If the load exceeds 10A, reduce the load or replace the breaker with a higher rating. Inspect the wiring for shorts.

Circuit breaker fails to trip during a fault.

Have the circuit breaker inspected or replaced by a qualified electrician. There might be internal damage or failure.
