FKG2 without enclosure
FKG2 with enclosure
Generator Circuit Breakers for power plants from 50
to 200 MW; 5,000 to 9,500 A; 63 KA
‘The FKG2 isthe only Generator Circuit Breaker with a fully spring
‘operated mechanism that has been used with highly proven reliabilly
‘on all AREVA T&D switchgears for decades,
FKG2 provides you with a compact and flexible design (various
positions of the mechanism and terminals) and is naturally cooled
> with enclosure for 8,400 A applications
> without enclosure for 8,500 A applications
FKG2 Generator Circuit Breakers are tested and manufactured in
‘accordance with Intomational Standard IEEE C37.013 (1997),
Al our units are ISO 9001: 2000 certified.
