Abstract

1,269,037. Protective systems. GENERAL ELECTRIC CO. 4 Feb., 1970 [24 Feb., 1969], No. 5340/70. Heading H2K. The current limiting circuit-breakers of Specifications 1,196,799 and 1,196,797 (Heading H1N) are used as the main, feeder and branch circuit-breakers in a distribution system, the short-circuit current-responsive devices of the circuit-breakers being adjusted so that the branch circuit-breaker responds to the lowest current value and the main circuit-breaker responds to the highest current value.
