Definitions

the invention relates to a multi-phase circuit breaker, which is composed of several individual switches in a shell design, which isolates all poles in the event of overload on only one individual switch by coupling the individual switches, and in which each individual switch is completely formed in its shells, including an overload release element and switching mechanism.
a circuit breaker of this type which is known in practice is composed of individual switches, such as those e.g. are known from DE-OS 33 39 398.
the known circuit breaker is a circuit breaker in which the individual switches are designed for certain overload currents. It is known per se (DE-OS 35 45 930) to use assemblies for circuit breakers for the construction of motor circuit breakers.
the motor protection switch has a current range setting device which comprises an actuating member and a current scale assigned to it. In the known motor protection switch, only a single switching mechanism is provided. The production of this motor protection switch is expensive compared to the production of the known circuit breaker of the type mentioned.
the object of the invention is therefore to provide a circuit breaker of the type mentioned, which is completed in a simplified manner to a motor protection switch with current range setting.
the circuit breaker according to the invention is solving this problem, characterized in that a motor protection switch current range setting device is provided which has an actuating member and a current scale associated with it, and that this engages an adjusting device with an adjusting member in each individual switch.
the individual switches known per se are used, which are manufactured in large numbers and therefore inexpensively. Although only one rear derailleur is required per se, individual switches with one rear derailleur each are used for reasons of profitable production.
every individual switch is assigned its own current range setting device. Rather, a single current range setting device is provided, which is modified in such a way that it acts on each individual switch at the same time.
a simplified current range setting device which forms a functional unit, is added to the multiphase circuit breaker of the type mentioned at the outset. The same components are used for a circuit breaker and a motor protection switch - Coil block, bimetallic device, arcing chamber and also switchgear - used.
the actuator is e.g. an angle lever with sliding pivot bearing. It is particularly expedient and before geous if the adjusting member is a wedge structure with each individual switch. This adjustable wedge structure is simple to manufacture and requires little space. By shifting the wedge structure transversely to the working direction of the overload release element, the distance between it and the release element of the switching mechanism is changed.
the adjusting members are carried by an intermediate guide piece which is slidably mounted in the shells of the individual switches.
This intermediate guide piece is arranged parallel to the row of overload release elements and parallel to the row of switching mechanisms in the individual switches arranged next to one another and thus displaceably transversely to the working direction of the overload triggering elements and switching mechanisms.
the wedge-shaped adjustment members are pivotally suspended on the intermediate guide piece in the working direction of the overload release element.
a shift of the individual switches to each other, which also causes a change in the position of the intermediate guide piece does not have the effect that the distance between the overload release element and the release element of the switching mechanism is changed.
the actuator is usually stored in the shell of one of the individual switches. It is particularly expedient and advantageous if the actuating member is mounted in a wall piece which is subsequently inserted into the shells of at least one individual switch. This simplifies the assembly of the circuit breaker.
the actuator is preassembled on the wall piece and the intermediate guide piece can be installed via the opening of the shell to be closed by the wall piece.
each individual switch can be operated manually.
Overload means both an overcurrent and a short-circuit current.
the motor protection switch is mainly used to protect a three-phase motor.
the actuator is e.g. a pin guided in a groove or an eccentric.
the invention is not limited to a specific embodiment of the overload individual switch in a shell construction.
a coil block 2 or electromagnetic release which carries a fixed contact piece 3, in a housing 1.
a quenching chamber 4 Below the coil block 2 there is a quenching chamber 4 and then an arc baffle 5, which carries a bimetal or overload tripping element 6 on its side facing away from the quenching chamber, which is adjusted by means of a screw device 7 mounted in the housing 1.
a connector 8 is connected via a heating winding 9 and / or a flexible connection to the overload release element 6.
a connecting line 10 closes the circuit via a movable contact piece 11, the fixed contact piece 3 and a coil winding 12 to a connector 13.
the movable contact 11 carries a switching mechanism 14, which consists of a locking lever 15 and a pawl 16.
the pawl 16 is connected by means of a bracket 17 to a switching element 18, whereby a link chain is formed, which closes or opens the circuit when the switching element is operated manually.
the adjusting device is shown in more detail in FIG. 4.
An intermediate guide piece 21 or adjusting slide carries rotatably suspended in a bearing 23 adjusting members 19 which, on their sides facing the triggering elements 6, have a rising surface 24, viewed parallel to the triggering elements, viewed from the direction of the cover to the triggering elements, that is to say they have a wedge shape.
the intermediate guide piece 21 is driven by an actuator 25 designed as an adjusting eccentric, which is rotatably mounted in a wall piece 20 and has an eccentric pin 26, and can be displaced transversely to the working direction of the triggering elements 6.
the intermediate guide piece 21 moves without play in a recess in the housing 1, which is achieved according to FIG. 3 by the suspension of tongues 27 located on the intermediate guide piece.
the at the free end of the tongues 27 and opposite cams 28 are arranged so that they always move only in a recess of a housing part, so do not have to overcome a separation point.
the adjusters 19 are suspended on arms 29 of the intermediate guide piece 21 such that two arms 29 of the intermediate guide piece 21 each encompass the adjusting members 19 in the displacement device without play.
the positioning of the adjusting members 19 in the arms 29 of the intermediate guide piece 21 can be done in a variety of ways.
the adjusting members can also each comprise a fork of the intermediate guide piece in the form of a fork.
the intermediate guide piece can also be actuated via a pin.
the wall piece 20 would have a linear scale, instead of an arcuate scale 30 shown in FIG. 1.
the wall piece 20 has a resilient latching tongue 31 according to FIG. 8. 3) and at the same time, the wall piece and thus the entire adjusting device is fixed at a defined point in the direction of displacement by means of a thickened part 34.
Two tongues 33 are rigid and engage behind on the outer parts of the housing only by pushing the complete individual switches together during final assembly.
the housing of the circuit breaker is made of three assembled in self-contained individual housings 22 and held together in a manner known per se.
Each individual housing 22 is composed of two different shells 35 and 36.
the switching mechanisms in the adjacent individual housings 22 are coupled to one another in a manner not shown in detail, but in a manner known per se, so that when a switching mechanism is triggered, the neighboring switching mechanism is also triggered.
the wall piece 20 extends to all individual housings 22, which facilitates the insertion of the intermediate guide piece 21. This is provided with an elongated hole 37 in which the pin 26 engages.
