29 METHOD AND APPARATUS FOR CONTROLLING A CIRCUIT BREAKER IN AN ELECTRICAL ENERGY SUPPLY NETWORK US15697657 2017-09-07 US20180082816A1 2018-03-22 HANS-JOACHIM HERRMANN
A method and an apparatus for controlling a circuit breaker in an electrical energy supply network. A switching signal is generated by a protective or control device of the energy supply network and the switching signal is transmitted to a control unit of the circuit breaker. The control unit is caused to open the switching contacts of the circuit breaker upon reception of the switching signal. In order to ensure a switching operation which is as fast as possible even in those energy supply networks in which phases of the current to be switched by a circuit breaker which are free of zero crossings can occur, a current flowing through the circuit breaker is recorded and is checked for the occurrence of zero crossings. The transmission of the signal for opening the switching contacts is prevented until at least one zero crossing has been detected.

32 Trip device of circuit breaker US371497 1999-08-10 US6054912A 2000-04-25 Shozo Kaneko; Takeshi Yura
A trip device of a main circuit breaker is provided which causes only a branch circuit breaker to be set into a tripped state when an abnormal current occurs at a load of the branch circuit breaker while keeping a closed state of the main circuit breaker. The trip device of the circuit breaker has a structure including a trip latch mechanism for opening switching contacts, a stationary core, a movable core which is attracted to the stationary core to release the latch mechanism of a trip lever, an operating pin for interrupting movement of the movable core while the movable core is attracted, an operating spring charged with force when the movable core is attracted, and an inertia roller holding the operating pin, kicked when the operating spring discharges the force, and moved to a position which does not interrupt movement of the movable core. Accordingly, this structure allows a selective tripping system to be implemented simply with small size and low cost.
33 Circuit breakers with PTC (Positive Temperature Coefficient resistivity US918768 1997-08-25 US5886860A 1999-03-23 William Weizhong Chen; Colin Cornhill; Andy Haun; Gary Scott; Manzoor Ali; William Rezac; Kevin James Green
A Positive Temperature Coefficient Resistivity (PTC) element has a resistivity that increases as the temperature increases. Circuit breakers having PTC elements can achieve better overload and short circuit protection than existing products. Breakers with PTC elements can also be combined with ground fault detection circuits to activate the circuit breaker under ground fault conditions that are less severe than the overcurrent conditions that would normally activate the circuit breaker. A shunt trip assembly incorporating a PTC resistor reduces the required power rating of the clearing switch.
34 Electromagnetic switch US291255 1988-12-28 US4935711A 1990-06-19 Derk Van der Scheer; Johannes T. Hopman; Jan W. Hoekstra
An electromagnetic switch with a housing provided with at least one magnet system, comprising a stator body of magnetic material having an oblong chamber accomodating a movable armature of magnetic material, with an exciter winding for the excitation of a magnetic field in the at least one magnet system. A swingably supported first arm which can be brought into motion under the influence of the excited magnetic field. To actuate a pair of contacts a swingably supported second arm is provided and on each of the first and second arms one end of at least one leaf spring acts. The first and second arms extend on either side of the chamber at right angles to the lengthwise direction thereof in such a way that each of them can swing about their support point in the direction of the armature which is movable in the chamber between the arms. The free end of the first arm is coupled to the armature, which has an operating element which acts on the second arm.
35 Magnetic trigger for a selectively operative switch US132834 1987-12-14 US4808952A 1989-02-28 Jorg Berner; Markus Anliker; Willy Feller; Werner Breer
There are arranged at a magnetic trigger for a selectively operative switch, a plunger-type armature, a pivotable armature and a tripping device. A plunger of the plunger-type armature acts directly upon a movable contact of a pair of contacts and the plunger-type armature is actuated using a magnetic coil or winding when the current flowing through the magnetic coil at least corresponds to a predetermined threshold current for opening the contacts. A pivotable armature is actuated by the plunger-type armature and redirects the magnetic return flux. The tripping device acts upon a switch lock mechanism and is switched into or out of the magnetic return flux by the plunger-type armature. The degree of overlap between pole shoes of the pivotable armature and of the tripping device is preselectable by an adjusting screw. There is thus realized a current-dependent, selective tripping of the switch lock mechanism.

38 Toggle lever switching mechanism for an automatic switching apparatus including a low-voltage tripping device US673384 1976-04-05 US4024366A 1977-05-17 Gerhard Hartwig
A toggle lever switching mechanism for an automatic switching apparatus including a housing and a low-voltage tripping device. The switching mechanism includes at least two toggle levers pivotally joined to each other at one end at a toggle joint and operatively connected to an actuating member for the switching mechanism by means of a spring member. The other ends of the toggle levers are pivotally coupled to a movable contact member of the switching apparatus and to a support lever which engages a latching pawl of the switching mechanism. The improvement of the invention comprises a support lever which is pivotally mounted in the switching mechanism housing at one end thereof and is pivotally coupled to one of the toggle levers at a point intermediate the ends thereof. Stop means are disposed in the switching mechanism housing for engaging and limiting the movement of the support lever so as to prevent the support lever from engaging the latching pawl during initial movement of the actuating member from a contact-open position to a contact-closed position of the switching apparatus.
