Standard
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 at our service facilities.
They cannot be installed in the field or by distributors.
So we don’t want to make any more work for you, but we MUST
get it right the 1st time!
Accessories can be identified by small labels on the
breaker, with part numbers such as
a.
(u-nzm6) (230, 60) Indicates under voltage
trip which needs 230 volt 60hz applied to turn the breaker
on.
b.
(a-nzm6) (230,60) Indicates shunt trip which
needs 230 volt 60hz applied to turn the breaker off.
c.
(rhi, nhi, ahi -xx) Would be auxiliary
contacts.
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.
