Behaviour – Tripped circuit breaker

What to do if the circuit breaker in your home is tripped

The EFUSE must be used only in places where the electrical power supply is protected by a standard circuit breaker with a maximum rated current of 16A (e.g. a type B16 or smaller) or an equivalent safety device. On the rare occasion that this safety device has been tripped, you should first check whether this is due to the device connected to the EFUSE. To do that, unplug the EFUSE and the device it is protecting from the mains power supply and reset the circuit breaker.

If the circuit breaker is tripped again, there is a fault that is unrelated to the EFUSE and the device it is protecting. In this case, follow the usual procedures that apply when a short-circuit occurs that is unrelated to your device and the EFUSE, or contact a specialist. If the circuit breaker is not tripped again, you can assume that an exceptional short-circuit has taken place in your device. To check this when you are using the external version of EFUSE, unplug the EFUSE from the device and then reconnect the EFUSE to the mains power s ply. The red LED indicates that the EFUSE has been tripped.

To ensure that the exceptional short-circuit in your device has not also caused damage to the EFUSE, you can connect the EFUSE to another device with the same connector type. When the red light is showing on the EFUSE and the reset button has not been pressed, this second device should not work. However, if the red light is showing but the second device does work, this shows that the EFUSE has been damaged. In such a case, the EFUSE must not be used and must be returned to your specialist dealer for repair. If you are using the internal version of the EFUSE, there is no simple troubleshooting method that you can carry out yourself. Please return your device, together with the installed version of the EFUSE to your specialist dealer for repair.
