46,557 VACUUM CIRCUIT BREAKER APPARATUS HAVING ELONGATED SUPPORT MEMBERS Vacuum circuit breaker apparatus is taught having a pair of parallel, spaced apart, elongated support members. At one end of the parallel spaced apart support members is disposed the operating mechanism for opening and closing the vacuum circuit breaker contacts. Disposed along the remaining elongated portion of the parallel spaced apart-support members in tandem arrangement with respect to the operating mechanism are three vacuum interrupters. The pivotal linkage pins for the operating mechanism of the vacuum contacts are placed in the elongated support member in appropriate places. Likewise pivotal support pins and the line for the contact moving linkages are also disposed in the elongated support pieces. |
