 Easy to maintain & environmentally friendly:
o 100% Air insulated, no SF6 gas used
 Silver-plated copper phase bus bar for
permanent connection to the facility
 Phase barriers physically isolate each phase to
minimize the possibility of phase-to-phase
contact
 No need to tape or boot field cable terminations.
 Fixed mounted vacuum circuit breakers
 High-speed operation – complete fault clearing in
less than 3 cycles

 Hermetically sealed vacuum interrupters protect
contacts from corroding elements and
contamination
 Optional: Fixed Mount or Drawout Voltage
Sensing
 Your choice of generator protective relay
functions
 Optional: Slide out circuit breaker removal
design, installed on rollers
o Rollers are provided to simplify the field
removal of the circuit breakers
o Modular, slide-out design of the major
power switching components to minimize
the down time, should component
replacement or repair be needed
 Optional: Inline visible air-disconnect switch,
pad-lockable in open and/or closed position, to
ensure personnel safety during power system
service, maintenance, and repairs

01 Vacuum Circuit Breakers
02 Silver-Plated Copper Bus
03 Isolated Phase Barriers
04 Field Grounding Provisions

Final construction and configuration may vary by project requirements.

Key Advantages

Operator Safety

Metal-enclosed dead-front construction and remote operation help reduce personnel exposure.

SF6-Free Design

100% air-insulated construction eliminates the use of SF6 gas.

High-Speed Protection

Complete fault clearing in less than three cycles.

Serviceability

Optional slide-out components simplify maintenance and equipment replacement.

How It Protects

Protective relays monitor generator and system conditions and command the vacuum circuit breaker to isolate the generator when a qualifying fault or abnormal condition is detected.
