Eaton Cooper Power NR Series, Maintenance Instructions Manual

Page: 19 / 24

The service parts and hardware listed and illustrated include
only those parts and assemblies usually furnished for repair
or involved in the maintenance procedures described in
this manual. Further breakdown of listed assemblies is not
recommended.
Dimensions of all common hardware parts have been
carefully checked so that they may be locally acquired. The
suffix letter of the 14 character catalog number of common
hardware parts code the plating of the part:
A - No plating; raw material
H - Silver
M - Black oxide
Q - zinc + chromate
Y - Zinc + chromate
Z - Electro zinc + bronze irridite
To assure correct receipt of any part order, always include
switch type and serial number. Because of Eaton's
continuous improvement policy, there may be instances
where the parts furnished may not look exactly the same
as the parts ordered. However, they will be completely
interchangeable without any rework of the switch.
