Abstract

688,948. Switch cases; switchgear structures. ETABLISSEMENTS MERLIN & GERIN. Jan. 22, 1951 [Feb. 10, 1950], No. 1614/51. Class 38(v) [Also in Group XXXVI] The thick-walled casing 1 of a flame-proof air circuit-breaker is connected to a thin-walled bus-bar chamber 2, the bus-bars 3 being embedded in quartz crystals covered by a plate 5 which may be a phenolformal type resin. The cable-entry box 12 of a circuit-breaker (Fig. 2) may be similarly filled and provided with a plate 16.
