THE CIRCUIT BREAKERS DESCRIBED IN THIS
BOOK ARE DESIGNED AND TESTED TO OPERATE
WITHIN THEIR NAMEPLATE RATINGS. OPERATION
OUTSIDE OF THESE RATINGS MAY CAUSE THE
WARNING
EQUIPMENT TO FAIL, RESULTING IN DEATH,
BODILY INJURY AND PROPERTY DAMAGE.
ALL SAFETY CODES, SAFETY STANDARDS AND/OR
REGULATIONS AS THEY MAY BE APPLIED TO THIS
TYPE OF EQUIPMENT MUST BE STRICTLY
ADHERED TO.

KEMA tested to applicable standards ANSI C37.04 - 1979, C37.09 - 1979, C37.06 - 1997 (operating Duty Sequence CO - 15s - 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).
For Force Air Cooled Fixed Breaker Applications, consult Eaton.
The ANSI C37.06 Standard requires 150kV BIL. If higher BIL levels are required, please refer to the “C” breakers.
If you require 50 ms (3 cycle) interrupting time, please refer to the “C” breakers.
The Standard Breaker is not rated for capacitor switching. If you require capacitor switching, please refer to the “C” breakers.
