All circuit breakers are tested to 60 Hz; however, they can also be applied at 50 Hz with no derating.
b
Consult the Consulting Application Guide CA08104001E sections 1 and 5 for further information.
c
Also 3-second short time current carrying capability.
Table 6. (ANSI Standards
a
) type VCP-WXC circuit breaker through 15 kV rated symmetrical current basis (standard ratings).
See Figure 23 for control schemes and diagram that apply to this breaker. This breaker differs from the standard breaker with the addition of a third motor cut-off switch and
addition of two wires.
