Abstract

420,590. Switch cases. FELTEN & GUILLEAUME CARLSWERK AKT.-GES., 24, Schantseustrasse, M³lheim, Cologne, Germany. Sept. 28, 1934, No. 27870. Convention date, Oct. 24, 1933. [Class 38 (v)] In a protective switch with fault current coil and testing device, in which the front part of the casing 1 serves entirely as a connection chamber, the fault current coil 10 and testing resistance 11 are mounted in the front connection chamber in such a manner that they can easily be replaced. For this purpose, contact lugs 13, 14 are arranged to project into the connection chamber through openings in an insulating plate 9 which separates the connection chamber from an inner casing 2 carrying the switch mechanism. The testing resistance 11 is held between the contact lugs 13 by spring action, and the fault current coil 10 is screwed on to the contact lugs 14.
