Definitions
- the invention relates to a low-voltage circuit breaker with an electronic overcurrent release and with release magnets, which release a latch due to control by the overcurrent release or by a separate signal for releasing closed switching contacts, the overcurrent release and the release magnets being combined to form a protection module.
- a circuit breaker with the features mentioned has become known from US 4,700,161. This is part of a well-known compact design with molded plastic housing and rocker arm drive (MCCB). To make it possible to replace or retrofit components of the tripping magnets, they are accessible on the operating front of the circuit breaker after a cover has been removed.
- the electronic overcurrent release does not have its own control panel due to the compact design of the circuit breaker. It also corresponds to the design of compact circuit breakers that a trip is not recognizable to the user by a separate display element but by a special position of the outer handle of the rocker arm drive.
- the reset (RESET) required to switch the circuit breaker on again is also carried out using the handle of the rocker arm drive.
- Electronic overcurrent releases and trip magnets are used in the same way for low-voltage circuit breakers of the open type (PCB) that are used Compared to the type with rocker arm drive, they are suitable for higher nominal currents and higher switching capacity, as well as a storage drive.
- the overcurrent releases of these circuit breakers also offer the possibility of setting all the essential parameters in order, for example, to be able to adapt the protective action of the circuit breaker to the properties of a consumer.
- the overcurrent release is provided with its own control panel, which is integrated in the control panel of the circuit breaker and on which the setting elements are accessible.
- the reset after tripping is carried out here by a separate organ, which is located near the operating front of the overcurrent release (catalog 3WN6, 1995, page 2, Siemens publication E20002-K1801-B401-A1).
- the invention is based on the object of accommodating trip magnets in a circuit breaker of the last-mentioned type in a space-saving manner and of arranging their display and reset elements on the operating front of the circuit breaker in an overview.
- this object is achieved in that the electronic overcurrent release has a control front in a manner known per se, which is accessible on a control panel of the circuit breaker, and in that the tripping magnets are attached to the side of a housing of the overcurrent release facing away from the control front.
- FIG. 1 shows a side view of a protection module, consisting of an electronic overcurrent release and an assembly of release magnets.
- FIG. 2 shows the upper part of an operating front of the protection module according to FIG. 1.
- the protection module 1 consists of an electronic overcurrent release 2, the housing 3 of which is designed in such a way that trip magnets 4 can be accommodated in whole or in part in the gradation.
- the trigger magnets are combined in a known manner to form a magnet assembly.
- a trigger magnet to be activated by the overcurrent release 2 as well as an undervoltage release and a shunt release can be present.
- These additional tripping magnets can be activated via their own circuits.
- a display element 7 and a are
- Reset element 8 is provided for the release magnet 8 influenced by the overcurrent release, and the same display and control elements 9 and 10 for a shunt release, which can be excited, for example, when a high-performance safety fuse connected in series with the circuit breaker responds.
- the magnet assembly shown in FIG. 1 with the release magnets 4 can be equipped as required, as is known per se, and can additionally have signaling switches 11 in order not only to indicate a response of the release magnets 4 mechanically, but also to be able to report them electrically ,
- a problem-free interaction of the release magnets 4 arranged on the rear side of the housing 3 with the display and reset elements located on the operating front 5 is made possible in that the control panel 5 protrudes somewhat beyond the housing 3 and thereby from the magnet assembly, which also somewhat protrudes beyond the housing 3 Display and reset serving pins or plunger can be arranged.
- the display and reset elements of more than two trigger magnets 4 can also be arranged in the display field 6. If, as indicated in FIG. 2, tripping magnets 4 are arranged next to one another, this simplifies the accommodating of the display and reset elements 7, 9 or 8 and 10.
- the low-voltage circuit breaker, which is equipped with the protection module, has been added to the Figures are not shown separately, since it is of a design known per se. listen, e.g. B. corresponding to the mentioned Siemens print.
