CESI tested to applicable ANSI Standards C37.04 - 1979, C37.09 - 1979, and
C37.06 -199X. Consult Eaton for CESI reports on file. Operating duty
cycle CO-15 seconds-CO. Operating time values: opening 33-55 ms,
closing 50-60 ms and reclosing 18 cycles (300 ms).
(A) Tested at 28.5kV RMS. (B) Tested at 29.2kV RMS.
K=1.0, therefore E = E/K and I = KI. Consult Application Data 32-265 for further
information.
Optional interrupting time of 3 cycles is available.
Also maximum interrupting rating.

(1) 3 cycles
(2) Close & Latch Current for 1 200A Type 150 VCP-W 25C is proven at
15kV. For sealed interrupters at high altitudes, switching voltage is
not de-rated.
(3) For higher RRRV contact Eaton for more information.
(4) Breaker tested to 2700A single bank switching for momentary
load (Thermal derating must consider harmonic content of
current waveform).
(5) Breaker tested to 1 270A back-to-back switching for momentary
load (Thermal derating must consider harmonic content of
Current waveform)
(6) Capacitor Switching Ratings are proven at 15kV. For sealed
interrupters at high altitudes, switching voltage is not de-rated.
