Close & latch current for 1200 A Type 150 VCP-W 25C is proven at 15 kV. For sealed interrupters at high altitudes, switching voltage is not de-rated.
c
For higher RRRV contact Eaton for more information.
d
Breaker tested to 2700 A single bank switching for momentary load (Thermal derating must consider harmonic content of current waveform).
e
Breaker tested to 1270 A back-to-back switching for momentary load (Thermal derating must consider harmonic content of current waveform)
f
Capacitor switching ratings are proven at 15 kV. For sealed interrupters at high altitudes, switching voltage is not de-rated.
