The circuit breaker system further includes a circuit breaker, which can be repositioned between a first plug-in position forming a series circuit with the switch and a second plug-in position forming a parallel circuit with the switch.

Abstract: A current distributor includes a common, uninterrupted first main busbar as a main current supply and a number of current distributor modules which are each associated with a respective circuit breaker and can be disposed in a row along the main busbar. The current distributor module or each current distributor module has a first connection line for supplying current to a load circuit. The current distributor module or each current distributor module has a housing, a slot formed on a front side of the housing for plugging on an associated circuit breaker, and a first channel which passes through the housing in a transverse direction for accommodating the first main busbar. A first contact opening of the slot corresponds to the first channel and a second contact opening of the slot corresponds to a housing receptacle for a connection socket of the first connection line.

The system includes a control device used to control each load output according to the input signal that is disposed on an associated input, which can be configured such that each input can be allocated to any particular load output by logical interlinking. The control device is formed from a plurality of hardware-sided identical base modules.

Abstract: A circuit breaker includes a bimetallic snap-action disk fixed to a bimetallic connection disposed in the vicinity of a fixed contact connection inside a coverable housing. The bimetallic disk has a contact end with a contact superposed with a fixed contact of the fixed contact connection in such a way that a contact is established. When the contacts are opened, a spring-loaded isolating slide moves between the contacts. The isolating slide has an illuminated push button for reliably identifying a disconnection.

Abstract: The invention relates to a simulation switch for incorporation into a flight simulator and to the simulation of an excess-current circuit breaker which can be manually actuated using an actuating element (10). The inventive simulation switch comprises a switching mechanism that is identical to the switching mechanism of the excess-current circuit breaker (9) for opening and closing a switching contact (2, 4), in addition to an electromagnetic release device (20) for releasing the closed switching contact (2, 4) by means of a control current (i).

Abstract: A circuit breaker has a threaded collar fixed on a breaker housing and an approximately cylindrical actuating element displaceably guided in a bore of the threaded collar and partially protruding from the breaker housing for manual push-pull actuation in an advantageous way on the actuating side. In order to seal the circuit breaker, a sealing ring seals an annular gap formed between the wall of the bore and the circumference of the actuating element.

Abstract: A door latch is particularly suited for a washing machine door. The device has a pivotally mounted rotary catch for latching onto a locking element and a pivotally mounted blocking or arresting element. The latter is pivotally mounted between a latching position that latches the rotary catch and an unlatching position that releases the rotary catch. The arresting element can be actuated by a bimetallic adjusting element, which can be heated by a heating element, and by an actuator system that, at the same time, is actively connected to the turning catch in a direct manner. A torque component effected on the arresting member by the actuator system is greater in value that a torque component introduced by the bimetallic adjusting element.

Abstract: The invention relates to a method for detecting accidental arcs (arc tracking) on a cable (1), especially on a cable of an aircraft electrical system. According to said method, an alternating current signal (I(t)) that has been detected is sampled time-discretely and a trigonometric function (I(k)) imitating the alternating current characteristic is determined by interpolation of a number of sampling values (y(k)). The current alternating frequency (?) is then derived from this trigonometric function. The result of a comparison of the current alternating current frequency (?) and a set or reference frequency (??) is used to determine the presence of an accidental arc (ISA,IGA) and a warning signal (Sarc) is optionally generated. A device which functions according to this method is advantageously integrated into a circuit-breaker (7) for the aircraft electrical system, so that the latter is equipped to detect and deactivate accidental arcs that occur on the electrical system cable (1).

Abstract: An undervoltage tripping device for a multipolar low-voltage switching device is described. The tripping device contains an electromagnetic tripping mechanism for effectuating a tripping of the multipolar low-voltage switching device given a drop below a predeterminable voltage limit value. The tripping mechanism has a magnetic circuit with a spring-loaded armature and a trip coil including a number of winding portions corresponding to a number of phases of a multiphase power supply circuit. A rectifier bridge is powered by the multiphase power supply circuit. The rectifier bridge has a number of rectifier branches corresponding to the number of the phases of the multiphase power supply circuit. The rectifier bridge is connected to the tripping mechanism and the rectifier branches jointly power the tripping mechanism. The tripping mechanism effectuates an all-pole tripping of the low-voltage switching device given a failure of one of the phases of the multiphase power supply circuit.

Abstract: A circuit breaker for protecting electrical circuits, particularly in motor vehicles, includes a flat housing, which comprises an insulating material and has two adjacent flat plugs. A bimetal that is embodied as a snap-action element and is fixed to a flat plug serves in contacting the flat plugs together, with the contact end of the bimetal being located in an overlapping position with the counter-contact. During a contact opening as stipulated by an overcurrent, a contact separator automatically travels into the space between the opened contacts, and can be returned from its contact-separating position by the external exertion of a force acting counter to the spring pressure. A manual release device, which diverts the contact end of the bimetal from its contacting position into its contact-opening position, protrudes from the breaker housing.

Abstract: An electrical functional device for use in the field of aviation, for example, a safety switch, is described. The functional device has a housing out of which a cylindrical fixing neck projects. The fixing neck contains, on an outer circumference thereof, a fine-pitch threading for screwing on a nut, and carries, at a distance from the end thereof that is attached to the housing, a radially protruding bearing flange. The bearing flange serves to hold the device in a fixed position, in which the fixing neck projects through a fastening hole of a wall element and is held therein against the bearing flange by a nut. The fixing neck is a one-piece part made out of plastic. It contains, between the end of the threading thereof and the bearing flange, an unthreaded shaft area, which is coaxial in relation to the fixing neck.

Abstract: A power distribution system includes circuits each having an electronic circuit breaker as a protection for short-circuits and/or overloads, and a clocked power supply unit. The clocked power supply unit is connected to the circuits and feeds power to the circuits. The electronic circuit breaker has a power stage and an adjustable current limiting device connected to the power stage. The adjustable current limiting device, in the event of an overload, when a first adjustable current threshold is exceeded, turns off the power stage after a first adjustable disconnection time has expired, and in the event of a short circuit, after a second adjustable current threshold has been exceeded, turns off the power stage after a second disconnection time has expired.

Abstract: The locking movement and/or the unlocking movement of a bimetallic drive of an electrothermally-controlled locking apparatus, for example for household-device doors, is or are driven by a separate bimetal member (10, 11) over only a first segment of its movement path. In the process, energy is supplied to the energy store (28) of a tipping over-center device until a dead-center position is attained, the energy being released as a moving drive for the remaining segment of the movement path when the dead-center position is exceeded, thereby cutting off the bimetal drive and stabilizing the locking member (2) in its end position.
