Switches for Use in Nuclear Power Plants
[

Dear Mr. Stefanck:
Thank you for your recent request for information about our limit switches for use in nuclear power plants.
t We are enclosing a copy of our Series EA80 General Catalog. We ave adapted two of our switch lines to make them suitable for use in a nucicar power plant. The two switch lines are the EA170 (D2400X) series shown on pages 11 through 18 of the catalog and EA700 (SL) series shown on pages 23 through 30.
The switches shown in the catalog are standard units, but the nucicar models..'g are mechanically and electrically the same as these shown. They vary only in the special materials which are used in their fabrication in order to make them suitabic for use in a nuclear power plant environment.
We are enclosing lists of the part numbers for the three types of switches in each line. Taking the D2400X series first, the EA170 __100 part numbers represent our standard switch and are cross-referenced with the old D2400X part numbers. This switch has a NEMA 4 enclosure and is suitable for'use -
in an ambient of' 900C, but is not suitabic for other than a general use, and is not satisfactory for use in areas that will see any unusual environ-mental conditions. This switch has been scismically qualified to IEEE-344-1975.
v-The EA170 __302 part numbers are shown on the second sheet, and these are modifications of the standard switch.
These switches are also scismically
~
qualified and are suitable for use in areas outside of the containment area 8 rads.
with a cumulative radiation dosage of 2 X 10 The EA180 part numbers are shown on the last page.
These are the switch models that are qualified to IEEE-323-1974, IEEE-344-1975 and IEEE-382-1972.

These units differ only in the materials used in their construction and are chosen to withstand the environmental conditions that may exist in the containment area.
The~SL (EA700) series switch is also available in three models for the various locations as described above. The EA700 represents the standard switch. The EA750 series is the switch modified for areas outside of the containment, and the EA740 is the qualified switch for use inside of the containment area.
As we discussed with you on the telephone, the EA700 is a standard limit switch, and is really not suitable for nuclear use.
The switch is seis-s mically qualified to IEEE-344-1975 by similarity, since the EA740 is quali-fied, and. the latching mechanism is the same.
The TA700 switch has a NEMA 4 watertight enclosure.
It has a maximum 6
' ambient rating of 90 c and can tolerate a radiation level of 1 X 10 rads.
0 "r -
The levers for use with these switches are shown on pages 35 through 38 of the
~
catalog. For use on switches inside of the containment area, we would re-commend the use of 1cvers with bronze arms and beryllium copper rollers.
If you require any additional information, please contact me.
Tours very truly, 1
