WARNING: If you suspect that the protection release is faulty, functions incorrectly or has generated an un-
wanted trip, you are strongly advised to strictly comply with the following instructions in
Measurements menu
1. Make a note of the type of protection that has tripped by accessing the LAST TRIP page if there is an external power supply
(Vaux or battery) or by pressing "i Test" if in self-powering mode.
2. Note down the type of circuit-breaker, number of poles, any accessories connected, In, Serial Number (see par. 14.4) and the
SW version.
3. Prepare a brief description of the opening (what LEDs and/or indications were displayed? when did it happen?, how many
times ?, was it always under the same conditions? what type of load? what voltage? what current? is the event reproducible?)
4. Send/communicate all the information collected, together with the circuit diagram for the circuit-breaker, to your nearest ABB
Customer Support service.
The completeness and accuracy of the information given to the ABB Assistance service will facilitate technical analysis of the
problem encountered, and will allow us to carry out all actions useful for the user rapidly.
WARNING: Letting a switch run with a fault that has not been remedied may lead to an apparatus malfunction
or shutdown. Remove the apparatus immediately until it can be inspected or repaired if this situation may lead
to personal injury, damage or is otherwise critical.
