| Salient Features of Switchgear Panel |
|
Fully compartmentalized construction with IP4x degree of protection externally and IP2X between compartments. |
| |
Emphasis on operator's safety : |
| |
|
When the door is in closed condition manual operations like ON, OFF, manual spring charging, Rack-in & Rack-Out can be carried out. |
| |
|
Foolproof mechanical interlock to prevent rack-in and rack-out of closed breaker. |
| |
|
Independent exhaust vent for all HT compartments. |
| |
|
Multiple guides for safe, sure and enduring self aligning power contacts. |
| |
|
Live parts are covered by automatic shutters when breaker is racked out. |
| |
|
Bus & line earthing switch (Optional). |
|
Separately lockable shutters for bus and cable side. |
|
Access to cable terminals from rear. |
|
Guaranteed voltage withstand without conductor insulation . |
|
Top lifting arrangement for panel. |
|
Conforms to IEC Standard. |
|
The breaker cannot be moved from test to service position unless the breaker compartment door is closed |
|
The breaker cannot be moved from test to service position or vice versa with breaker in closed condition. |
|
The breaker cannot be closed in-between test and service position. |
|
The breaker compartment door cannot be opened when the breaker is in service position or in between service & test positions. |

| Salient Features of 12kv Vacuum Circuit Breaker |
|
A Compact, Light, Weight construction, Optimized to give minimum Weight to KA ratio. |
|
Superior mechanical endurance limit Maintenance required only after 10,000 operations. |
|
|
A Unique 'U' shaped insulation barrier housing for the Vaccum interrupters, imparting maximum mechanical strength against electrodynamic forces and provides most effective phase to phase and phase to earth segregation. |
|
A screw type racking arrangement for easy insertion and withdrawl of the Circuit Breaker renders perfect contact pressure, independent of operator's Force |
|
A simple motor charged spring operating mechanism noted for its high performance reliability. |
|
A versatile mechanism capable of operating Vacuum Interrupters of any type . Hence, dependence on single source of Vacuum interrputers eliminated. |
|
Trip free mechanism suitable for repeated auto reclosing duty. |
|
Spring Charging time of less than 10 seconds. |
|
Totally enclosed construction for spring charging motor. |
|
Easy visual check of contact erosion. |
|
