Table 11: Type 3AH vacuum circuit breaker ratings (new "constant kA" ratings basis)
These ratings are in
accordance with:
ANSI/IEEE C37.04-1999

Footnotes:
1.
Maximum design voltage for
which the circuit breaker is
designed and the upper limit for
operation.
2.
K is listed for information
purposes only. For circuit
breakers rated on a "constant kA"
ratings basis, the voltage range
factor is 1.0.
3.
All values apply to polyphase and
line-to-line faults.
4.
Standard duty cycle is O - 0.3 s -
CO - 3 min. - CO.
5.
Standard rating interrupting time
is five-cycles (83 ms). Optional
rated interrupting time of three-
cycles (50 ms) is available
(except with 24 Vdc tripping).
6.
150 kV BIL is for drawout
applications. 200 kV BIL is for
type SDV6 with appropriate
construction.
7.
Continuous current capability
may be increased by the use of
forced-cooling (fan-cooling) in
the switchgear together with
increased bus bar capacity.
