
KEMA tested to applicable standards ANSI C37.04 - 1979, C37.09 - 1979, C37.06 - 1997 (operating Duty Sequence CO - 1 5s - CO). Typical operating time values: opening 45 ms, closing 75 ms, and reclosing
300 ms (18 cycles).

K=1 .0, therefore E=E/K and I=KI, refer to the Consulting Application Catalog for further information.

Rated and Tested also for Rapid Re-closing Capability O - 0.3s - CO.

Not rated for Rapid Re-closing.

At 23kV rms (Rated Max Voltage/K), Rated maximum symmetrical interrupting capability = 35kA rms (K x I).
