Abstract
428,923. Protective cut-out arrangements. FELTEN & GUILLEAUME CARLSWERK AKT.-GES., M³lheim, Cologne, Germany. Dec. 21, 1934, No. 36676. Convention date, Dec. 29, 1933. [Class 38 (v)] In a protective arrangement in which a fault-current coil a is connected at one end to earth and at the other end to a protecting conductor connected to apparatus in which dangerous voltages may arise due to failure of insulation or other causes, and in which a testing device is provided by means of which the coil can be temporarily disconnected from the protecting conductor and connected to individual phases of the supply, the coil a is connected to a contact spring d which is normally pressed against a fixed contact c connected to the terminal b of the protecting conductor by means of a spring- controlled two-armed switch lever e pivoted at f, the lever e normally engaging an abutment g in electrical connection with the contact c, so that there are normally two contact devices in parallel between the coil a and terminal b. The pivot f is also connected to the coil a through a resistance l. When it is desired to test the arrangement, the lever e is rotated in a clockwise direction, thereby disconnecting the coil from the terminal b of the protecting conductor and connecting the coil through the resistance l and a second lever n to one of the terminals p, q, connected to the phases of the supply.
