Gas System
The circuit switcher shall have a gas system constructed of rigid copper piping or 
a combination of rigid copper piping and flexible stainless steel tubing that allows 
each interrupter to be pressurized through a fill port. 
 
The gas system shall include the insulator and a color coded, temperature 
compensated density gauge that is visible from the ground and which is 
furnished with low-pressure alarm and lockout contacts. The density gauge must 
be at ground potential. Battery powered gas density monitors are not 
acceptable. 
 
The system shall be constructed such that the density gauge can be isolated 
from the interrupter to allow the low-pressure alarm and lockout contact set 
points to be verified. A means for refilling the system in the field without 
disassembling the circuit switcher must be provided. The device shall have a 
leak rate of less than 0.5% per year. 
 
3.06 Terminal Pads
Terminal pads shall be unplated aluminum with 4 hole NEMA drilling pattern for 
use with purchaser furnished terminal connectors. The terminal pads shall be 
reversible for mounting at the top, bottom, or either side of the interrupter. 
3.07 Operating Mechanism
3.07.01 Spring Operating Mechanism
Each circuit switcher shall be provided with a spring open-spring close 
mechanism capable of a duty cycle of O-0.3 seconds-CO-15 seconds-
CO. The spring shall be charged via an electric motor in 15 seconds or 
less. Pneumatic, hydraulic, or combination pneumatic/hydraulic 
mechanisms are not acceptable. Devices utilizing multiple mechanisms 
are not acceptable. 
3.07.02 Mechanism Housing and Control Components
An ANSI 70 gray painted steel mechanism housing shall be furnished 
and shall be provided with the following accessories: 
1. Electric spring charging motor 
2. Color coded, temperature compensated gas density gauge with 
low-pressure alarm contact and low-pressure lockout contact
3. Trip-close pistol grip switch 
4. Close coil 
5. Dual trip coils 
6. Anti-pump relay 
7. Local-remote selector switch 
8. A minimum of 10 spare non-adjustable auxiliary switch contacts 
factory set as 5 normally open (NO) and 5 normally closed (NC) 
contacts
