Vertical Interrupter Style Circuit Switcher
Product Specification Guide
1.0 SCOPE
This specification covers the design, manufacture, and testing of three pole, gang
operated vertical interrupter outdoor circuit switchers without integral disconnect.
2.0 STANDARDS
All outdoor circuit switchers shall be designed, manufactured, assembled, and tested in
accordance with the latest applicable ANSI, NEMA, and ASTM standards and
guidelines. If there are any conflicts between the ANSI, NEMA, or ASTM standards and
this specification the specification shall govern.
3.0 DESIGN REQUIREMENTS
3.01 Service Conditions
The circuit switcher shall be suitable for outdoor installation in electric power
substations under the following conditions:
3.01.01 Temperature
The circuit switcher shall perform in an ambient temperature range of
-40oC through +50oC.
3.01.02 Altitude
The circuit switcher shall perform at elevations up to 3,300 feet.
3.01.03 Seismic
The circuit switcher shall be capable of withstanding seismic loading of
0.2 g ground acceleration in any direction when installed on the
manufacturer’s furnished support structure and anchor bolts and with
flexible connections to the terminal pads. The circuit switcher shall
perform its specified functions during and after the seismic event.
3.01.04 Wind Loading
The circuit switcher shall be capable of withstanding wind loads up to
90 mph without loss of function.
3.01.05 Additional Requirements
If any site specific service conditions not covered in sections 3.01.01
through 3.01.04 exists (e.g. extreme cold temperature installation,
corrosive environment, high altitude installation, etc.) they will be defined
in the quotation request.
