Breakers have 3 power wires in (L1-L2-L3) on the top, and 3
power wires out (T1-T2-T3) on the bottom.
Any other control wires will indicate some sort of
modification accessory is installed!
By UL code breakers can only be modified at our UL Approved
They cannot be installed in the field or by distributors. In
order to get the correct breaker to you, it is imperative
that we have the correct information due to the wide variety
of options that may be installed on your current breaker.
Accessories can be identified by small labels on the
breaker, with part numbers such as
(u-nzm6) (230, 60) Indicates under voltage
trip which needs 230 volt 60hz applied to turn the breaker
(a-nzm6) (230,60) Indicates shunt trip which
needs 230 volt 60hz applied to turn the breaker off.
(rhi, nhi, ahi -xx) Would be auxiliary
If the labels cannot be read or to double check their usage
record all the terminal numbers that have control wires on
them, and your KMparts Specialist will advise you of
your best options.
Please note any of the above when ordering. Also check to
see if they are even used. If they are present but there are
no wires on them then chances are you don’t need them.
