What is the rating of the number of switching operations of Square D, 200 A, general duty, F-series safety switches?

Product Line:
GD SS

Resolution:
For safety switches, the standard for design and testing of the number of switching operations is governed by UL98 and NEMA KS-1. There are two separate tests: (1) Endurance Test, and (2) Horsepower-overload test. The below table shows the minimum number of operations required (OFF to ON to OFF) by UL and NEMA. For the endurance test, however, Square D F series safety switches exceed the UL and NEMA requirements by up to 3 times the total (see below table):
