Enclosed Insulated Main Bus

Steel Enclosed Main Bus Compartment:
- Epoxy coated silver-plated copper, with bolted connections covered by insulating boots
- Grounded metal barriers mitigate the risk of fault propagation between major component compartments
- Durable Industrial Vinyl Mimic Bus
- 1200A, 2000A, 3000A
Symmetrical Interrupting Capacity:
- 2.4kV-15kV: 40kA, 50kA, 63k
Optional Surge Arresters for main bus protection and individual incoming utilities/outgoing feeders
- Distribution Class
- Intermediate Class

Incoming Cable Barrier Chutes (as required)

Vacuum Circuit Breakers

High Performance, Draw-out vacuum circuit breakers go into metalclad compartment
- Circuit breakers are removable
Mechanical interlocks prevent withdrawal or insertion of the circuit breaker when main contacts are not open
Closing springs automatically discharge before moving the circuit breaker out of the enclosure
Circuit breaker cell mechanism maintains trip during insertion or withdrawal
Breaker cannot be electrically or mechanically closed when in the intermediate position
Supports three position indication:
- Connected
- Transport
- Test/Disconnected
All live parts are enclosed in grounded metal compartments & Breaker frame remains grounded during levering and in the connected position
Grounded metal shutters automatically cover primary connections when circuit breaker is removed from the Connected position
High-speed operation: Complete fault clearing in less than 3 cycles
Hermetically sealed vacuum interrupters protect contacts from corroding elements and contamination
Easy maintenance with contact wear indicator is provided on the vacuum interrupter moving stem
Available Vacuum Circuit Breaker Ratings are shown on Page 10 of the 15A-Series Metal-Clad Switchgear Brochure
