The equipment covered by this publication must be
selected for a specific application and it must be
installed, operated, and maintained by qualified
persons who are thoroughly trained and who
understand any hazards that may be involved. This
publication is written only for such qualified persons
and is not intended to be a substitute for adequate
training and experience in safety procedures for this
type
of
equipment.
The S&C Switch Operator-me CS-1A is a high-speed
operator having an operating time of 1.5 seconds
maximum. It is expressly designed for power operation
of S&C Circuit-Switchers-Mark V, as indicated in the
table below.
High-speed, high-torque power operation of S&C
Circuit-Switchers-Mark V, by means of the S&C Switch
0perator"Type CS-lA, is essential in order to attain
the two-time duty-cycle fault-closing ratings
of
30,000 amperes rms three-phase symmetrical,
76,500 amperes peak for Vertical-Break Style and
Integer Style models; and two-time duty-cycle fault-
closing ratings of 40,000 amperes rms three-phase
symmetrical, 102,000 amperes peak for Center-Break
Style models.
