        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.

        If a 3 pole 63A ,D curve 10kA MCB is no longer available in the C120 frame - what can I use instead?

        Code = A9N18511  3 pole, 15kA, 63A, (27mm wide)   

        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


        What is the new code for the 18364?

        The new code is now A9N18364

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

        Code =  A9E18073

        What is the part number for the 80 amp 3 pole and neutral 30mA RCBO, 10kA?

        The RCBO is made up with the 4 pole iC120N circuit breaker, part number A9N18372 plus add the 4 pole Vigi unit A9N18578

        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.

        Is there a lower amperage rated circuit breaker in the A9N18467?

        No, unfortunately not in that particular model.

        For further information please visit

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

        The part number is A9N18426

        What is the replacement for 18354, 4P pole , B curve, 100A, 10KA circuit breaker?

        We do not have a direct replacement for 18354. We have A9N18436 which is rated to 15KA.  A9N18436 is 4P pole , B curve, 100A, 15KA circuit breaker.

        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.
