Abstract (en)

[origin: EP0412401A2] The high-speed circuit breaker is provided with a roller lock which contains a latching roller and a drive roller. According to the invention, an elongator (10) is provided to release the latching mechanism. This high-speed circuit breaker can be used in switching devices for early identification of short-circuits and for microprocessor-controlled high-speed releasing. <IMAGE>
