Horizontal Interrupter Style Circuit Switchers
Product Specification Guide
1.0 SCOPE This specification covers the design, manufacture, and testing of three pole, gang
operated horizontal interrupter outdoor circuit switchers available with or without integral
motor operated vertical break disconnect switches.
2.0 STANDARDS The 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 REQUIRE MENTS
3.01 General
All control components required to operate the circuit switcher shall be mounted
at a height readily accessible from ground level without the use of elevating
devices.
3.02 Service Conditions
The circuit switcher shall be suitable for outdoor installation in electric power
substations under the fol l owing conditions:
3.02.01 Temperature The circuit switcher shall perform in an ambient temperature range of
-40oC through +40oC for 170 kV and below units and –30oC through
o
C for 245 kV units.(Consult factory for ratings outside the limits
+40
stated)
3.02.02 Altitude The circuit switcher shall perform at elevations up to 3,300 feet.
3.02.03 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 device shall perform its
specified functions during and after the seismic event.
3.02.04 Wind Loading The circuit switcher shall be capable of withstanding wind loads up to 90 mph without loss of function.
3.02.05 Additional Requirements If any site specific service conditions not covered in sections 3.02.01 through 3.02.04 exist (e.g. extreme cold temperature installation,

3.03.03 Source Supply Voltages Purchaser will supply the following sources for the motor, auxiliary, and control circuits:
1. Motor Voltage 48 VDC or 125 VDC
2. Auxiliary Voltage 120 / 240 VAC, 60 Hz, 1∅
3. Control Voltage 48 VDC or 125 VDC
3.04 Interrupter The circuit switcher shall use SF6 single gap puffer interrupters. Each interrupter shall be provided with a color-coded density gauge, an overpressure relief device, and a gas fill port. Arc assist type interrupters are not acceptable. Hermetically sealed interrupters are not acceptable due to the inherent dangers to purchaser’s personnel associated with handling fully pressurized SF6 devices during installation and also due to potential hazards encountered during transportation and offloading.
