    Abstract: A REMOTE CONTROL CIRCUIT BREAKER SYSTEM IN WHICH AN ELECTRONIC LOGIC UNIT IS BUILT INTO A MAIN ELECTROMAGNETICALLY OPERATED CIRCUIT BREAKER TO ACT AS THE CONTROLLING INTERFACE BETWEEN THE LATTER AND REMOTELY LOCATED PILOT CONTROL-CIRCUIT BREAKER UNIT. IN ADDITION TO DIRECTING MAIN CIRCUIT BREAKER OPERATION TO PROVIDE CLOSING AND OPENING OF THE SAME IN CORRESPONDENCE WITH THE OPERATION OF THE PILOT UNIT, THE LOGIC UNIT RESPONDS ON OVERLOAD TRIP OPEN OF THE MAIN CIRCUIT BREAKER TO SUBJECT THE PILOT UNIT TO A CONTROLLED VALUE OF SIMULATED OVERLOAD CURRENT AS WILL CAUSE THE LATTER TO TRIP OPEN AND AFFORD INDICATION OF THE OCCURENCE OF OVERLOAD TRIPPING IN THE MAIN CIRCUIT BREAKER. THE LOGIC UNIT ALSO AFFORDS COORDINATION OF A PLURALITY OF SUCH CIRCUIT BREAKERS IN A MULTIPHASE A.C SYSTEM SO THAT ALL WILL BE RESPONSIVE TO THE OPERATION OF A SINGLE REMOTE PILOT UNIT, AND WILL ALSO TRIP OPEN FOLLOWING OVERLOAD RESPONSE OF ANY THEREOF. FURTHER THE LOGIC UNIT AUTOMATICALLY FUNCTIONS IN THE EVENT OF A FAULT OCCURRING IN THE PILOT UNIT OR THE LINE CONNECTING IT WITH THE MAIN BREAKER TO LIMIT THE VALUE OF FAULT TO A NON-DESTRUCTIVE VALUE, AND PREVENT REPEATED CIRCUIT BREAKER CYCLING IN THE EVENT THE PILOT BREAKER FAILS TO OPEN. THE MAIN CIRCUIT BREAKER USES DOUBLE-BREAK CONTACTS AND PERMANENT MAGNET LATCHING TO IMPROVE ITS ARC RUPTURE WITHSTABILITY AND ELIMINATE THE NECESSITY OF CONTINUOUS ENERGIZATION OF ITS ELECTROMAGNETIC OPERATING COILS. THE OVERLOAD TRIP MECHANISM IN THE MAIN CIRCUIT BREAKER USES A LOW FRICTION LATCH, AND TOGETHER WITH AMBIENT TEMPERATURE COMPENSATION IN THE BIMETAL LATCH RELEASE ENCHANCES THE TRIP POINT PRECISION.

    Abstract: A remote control circuit breaker system in which an electronic logic unit is built into a main electromagnetically operated circuit breaker to act as the controlling interface between the latter and a remotely located pilot control-circuit breaker unit. In addition to directing main circuit breaker operation to provide closing and opening of the same in correspondence with the operation of the pilot unit, the logic unit responds on overload trip open of the main circuit breaker to subject the pilot unit to a controlled value of simulated overload current as will cause the latter to trip open and afford indication of the occurrence of overload tripping in the main circuit breaker. The logic unit also affords coordination of a plurality of such circuit breakers in a multiphase A.C. system so that all will be responsive to the operation of a single remote pilot unit, and will also trip open following overload response of any thereof. Further the logic unit automatically functions in the event of a fault occurring in the pilot unit or the line connecting it with the main breaker to limit the value of fault to a non-destructive value, and prevents repeated circuit breaker cycling in the event the pilot breaker fails to open. The main circuit breaker uses double-break contacts and permanent magnet latching to improve its arc rupture withstandability and eliminate the necessity of continuous energization of its electromagnetic operating coils. The overload trip mechanism in the main circuit breaker uses a low friction latch, and together with ambient temperature compensation in the bimetal latch release enhances the trip point precision.

    Abstract: One or two auxiliary switches are built into an electromagnetic relay. At each side of the relay, up to three auxiliary terminal inserts are molded in the relay base, each having a screw connector on the outside, and on the inside of the relay housing either a stationary contact, a wire (solder) connector, or both, thus affording a choice of a number of different auxiliary switching and relay coil connection arrangements as auxiliary functions to be performed simultaneously with the main power switching function of the relay. A support for a single-pole double-throw movable contact for the auxiliary switch is molded integrally on each of the left and right ends of the relay contact support that is rigidly secured to the relay armature for rocking movement therewith, and a movable contact is mounted on one or both supports and connected by a wire to the center auxiliary terminal at that side of the base. This provides an auxiliary switch structure having low contact bounce, more overtravel, direct drive, increased reliability and stability under vibration, and economy.

    Abstract: Improved contact structure for a relay. In a double-throw version, two spaced helical springs for each pole are partially compressed between a spring support and the movable contact to provide initial contact pressure. A contact support overlies the movable contact and screws secure all of these parts on top of a rockable armature. In a single-throw version, normally open or normally closed, only one helical compression spring per pole nearest the closing end of the contact may be used to provide initial contact pressure; and a dummy load is provided at the non-closing end of the movable contact to afford the same operating characteristics in the single-throw relay as in the double-throw relay since the operating mechanism uses an electromagnet and a permanent magnet to give equal contact forces at both ends of the throw.

    Abstract: An improved circuit for energizing and quickly deenergizing the DC operating winding of an electromagnetic contactor from sources of AC supply having a wide range of frequencies. It employs a full wave rectifier bridge, an auxiliary electromagnetic switch having a pair of low-inductance operating windings and normally open contacts. One of the auxiliary switch windings of high resistance is connected across the DC output terminals of the rectifier bridge while the other thereof of low resistance is connected across the same terminal in series with the normally open contacts and the operating winding of the electromagnetic contactor.
