Can the Tesys F-Line contactors be used to switch above 200Hz?

 Issue:
Customer is looking for a contactor to switch at 400Hz.

Product line:
LC1F, Tesys F

Environment:
n/a

Cause:
Documentation shows the LC1F can switch up to 200Hz. 

Resolution:
Switching high frequency currents overheats the contactors, so we need to de-rate the current value of the contactor.  Attached is a table for de-rating up to the LC1F630 contactor.  This table is for AC1 applications only. 

Note, due to the excessive conditions switching at higher frequencies we cannot commit to the electrical durability of the contactors.  In other words, the expected lifetime of the contactor will be reduced from the published curves.
