When purchasing the NZM7A-150N-NA , you will need the full part number off your model circuit breaker. 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! Accessories can be identified by small labels on the breaker, with part numbers such as a. (u-nzm7) (230, 60) Indicates under voltage trip which needs 230 volt 60hz applied to turn the breaker on. b. (a-nzm7) (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. |
