Abstract (en)
[origin: EP0303965A2] Electrical switchgear for fitment to installation circuit breakers. Known switchgears have one or more contact points on which a switch mechanism acts, the switch mechanism interacting with an adjacent circuit breaker. Differential operation of the contact points is thus not possible. To operate the switch poles 35, 45, a switch mechanism 36, 46 is provided in each case, which switch mechanisms are independent of one another and in each case have a coupling element which engages with the adjacent circuit breaker. In this case, each switch mechanism 36, 46 operates a switch pole 35, 45 which in each case is designed as a two-way switch. The arrangement permits the optional connection of the switch poles as opening or closing contacts and allows them to be operated differentially.
