Description

MODULAR SERIES-MOUNTED DEVICE SYSTEM DESCRIPTION The present invention relates to a modular DIN rail mounted device system for an electrical distribution board. Modular devices or installation devices, such as circuit breakers, residual current circuit breakers, time switches, D and DO fuses, DO switch fuse units, built-in switches and built-in sockets are designed for installation in electrical distributors or installation distributors. Such distributors can be found in practically every electrified building today. Conventional modular devices are described in particular by the German standard DIN 43 880. The devices with standardized sizes are mounted on top hat rails in a distribution cabinet. The power is tapped from the devices conventionally using screw or spring-loaded terminals. It is an object of the present invention to provide a DIN rail device system for an electrical distribution board to improve user-friendliness taking into account the desired applications. This object is achieved by a modular series-mounted device system according to claim 1, a series-mounted device module according to claim 21 and a connection module according to claim 22. Claims 2 to 20 relate to particularly advantageous implementations of the series-mounted device system according to claim 1.

The DIN rail device module and the connection module can in particular be separate modules that can be connected to one another. The DIN rail device module comprises a DIN rail device functional unit, an electrically insulating DIN rail device housing, one or more first contacts (preferably a first contact for a single-pole DIN rail device module or three first contacts for a three-pole DIN rail device module) arranged on a first side of the DIN rail device module, and one or more second contacts (preferably a second contact for a single-pole DIN rail device module or three second contacts for a three-pole DIN rail device module) arranged on a second side of the DIN rail device module opposite the first side. The DIN rail device housing can be made at least partially or completely from an electrically insulating material (e.g. from a plastic). The first and second contacts can each be electrical contacts that are electrically conductive. The first contacts can in particular be input contacts or output contacts of the DIN rail device module, and the second contacts can in particular be output contacts or input contacts of the DIN rail device module. The DIN rail device module can in particular be an residual current device or FI protection device, a circuit breaker or LS protection device, a fuse switch disconnector or fuse switching device, a load disconnector, an FI/LS switch in combination, an arc fault protection switch, an energy meter, a communication gateway or a motor starter. The connection module comprises an electrically insulating connection housing, one or more connection plug elements for plugging or detachably fastening the connection module onto a mounting panel or onto one or more device carrier modules of a modular mounting panel system of the electrical distributor and for detaching the connection module from the mounting panel or from the one or more device carrier modules, as well as one or more conductor elements, each of which has a first conductor end and a second conductor end, wherein the first conductor end and the second conductor end can each be contacted via a corresponding opening in the connection housing. It should be noted that the first or second conductor end of a conductor element can be end sections of the conductor element, but do not have to be; i.e. the first or second conductor end can also be intermediate sections of the conductor element, so that the conductor element extends beyond the first or second conductor end. The connection housing can be made at least partially or completely from an electrically insulating material (e.g. from a plastic). The one or more conductor elements can in particular be electrically conductive. The first and the second conductor end can each be exposed through the corresponding opening in the connection housing or protrude from the connection housing through the corresponding opening. When the connection module is plugged or detachably attached to the mounting panel, the DIN rail device module is positioned relative to the connection module along a The device is arranged so as to be movable in the insertion direction and can be inserted into an operating position by moving it along the insertion direction towards the mounting panel and can be removed from the operating position by moving it along the insertion direction away from the mounting panel. The DIN rail device module can also be locked or automatically locked to the connection module in the operating position, e.g. by means of a locking conne
