Abstract

1,060,964. Switchgear structures. SOC. COQ-FRANCE. April 28, 1964 [April 30, 1963], No. 17482/64. Heading H2B. A circuit breaker comprising a pair of fixed contacts 3, 5 and a bridging rod 4 inside a tubular insulating member 16 is pivotally mounted in a housing 1 and movable between a first position A in which an isolating contact 3a engages with a bus-bar contact and a second position B in which an earthing contact 3b engages an earthed bar 12. An intermediate position permits the circuit breaker to be withdrawn from the housing 1. A test terminal 21 is connected with the line contact 5 but is covered by a shutter which is removed only in the earthedposition B. In a modification (Figs. 3-5, not shown) a series connected fuse (17) is arranged to be shorted by an auxiliary contact (14a) on the circuit breaker when the latter is moved to its earthed position.
