| Salient Features of 12kv Vaccum 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 barries housing for the Vaccum interrupters ,imparting maximum mechanical strength against electrodynamic forces & provides most effective phase to phase and phase to earth segregation. |
|
A screw type racking arrangement for easy insertion & withdrawl of the Circuit Breaker renders perfect contact pressure ,independend of operator's Force. |
|
A simple motor charged spring operating mechanism noted for its high performance reliability. |
|
A versatile mechanism capable of operating Vacccum Interrupters of any type.Hence,dependence on single source of Vaccum interrupters eliminated. |
|
Trip free mechanism suitable for repeated auto re-closing duty. |
|
Spring charging time of less than 10 seconds. |
|
Totally enclosed construction for spring charging motor. |
|
Easy visual check of contact erosion. |
