            What is the part code for a 3 phase indicator pilot light?

             The part code is A9E18327

            What is the replacement for Merlin Gerin 15322 ?


            Are the A9N18359 and A9A26924 compatible?

            The ref A9N18359 is C120 MCB (Multi9 design in the white material).

            The ref A9A26924 is iOF auxiliary (Aciti9 design for iC60 MCB).

            I can confirm that the parts A9N18359 and A9A26924 are not compliant with each other


            Is it okay to terminate aluminium cables to the Acti 9 MCB's?

            Aluminium is more corrosive than copper and it can cause high resistance to the current flow over the period of time, So it is highly recommend to use the 27060 aluminium connection terminal if you are using Aluminium cables. 

            What is the new code for the 18364?

            The new code is now A9N18364

            What is the code for a RTC din rail mount timer?

            The code is A9E16067

            What is the alternative replacement for old merlin Gerin code 18073 ?

            Code =  A9E18073

            Wanted to know if A9N18524 can be used as 3 pole breaker instead of 4 pole?

            Yes, customer can use the 3 pole and leave 4 pole open.

            Is there a Din mounted 2P changeover switch?

            It is available in acti 9 range:
            A9E18074 which is 20A 250V rated.
            Please see attached wiring diagram.

            What is the part number for a B curve 125A 3P breaker

            The part number is A9N18426

            How many poles wide is the iC120 3 pole 80amp C/B - A9N18365?

            The A9N18365 is 3 pole wide but is 27mm per pole , thus meaning it will need a 4.5 pole wide enclosure 81mm
