  • the known circuit breaker has control inputs and signal outputs which are routed to a signal line or a bus interface. Consumers are connected only one pole with their respective positive pole to the circuit breaker, in particular, the negative poles of all consumers are directly connected to the negative pole of the power supply.
  • the adaptation of the tripping characteristic of the generic device to the consumers to be connected can often finally be made on site, ie during installation of the device.
  • This adjustment is typically made by selecting a suitable device from a variety of devices that have been factory-made with different tripping characteristics.
  • the devices may be factory-made with different nominal current values or with a different response time after which the device responds.
  • standard classifications for tripping characteristics have been created for this purpose, see, for example, VDE 0641 or VDE 0664. This requires, during assembly or maintenance of such devices, one copy of each type that may be required.
  • a fuse with a microprocessor which has a memory in which an I 2 t-curve is stored to simulate the heat load of the load to be secured, in particular their cooling after a response of the fuse.
  • the invention is therefore based on the object to provide a device which overcomes the disadvantages of the prior art.
  • the compiled from generic devices systems should be inexpensive to manufacture and maintain, easy to adapt to changing circumstances and yet permanently reliable in operation.
  • the tripping characteristic is determined at least by the parameter of the power or current integral, i. by the integral of the power or the current flowing through the load line over time, and the limit for that integral is directly adjustable by the adjusting means.
  • the integral can only be formed over an integration time that has lapsed in each case, for example over the past five seconds in each case; Longer values are no longer taken into account during integration.
  • the integration time can be constant, or also manually or automatically adjustable by the device, for example, depending on the connected consumer or the current load situation.
  • the actuator is a switch element that essentially shuts off the power and can reconnect. This can be done by a transistor, which also offers the possibility to regulate the load current, in particular to limit.
  • the adjusting means may be realized by a sliding or rotary switch or a sliding or rotary potentiometer which is connected to a microcontroller-based control unit and with which the parameters for the tripping characteristic can be set.
  • the adjusting element may have a tool engagement surface, so that it can only be operated with a suitable tool.

  • the device has a single adjustment means with which these two parameters are changed simultaneously.
  • a first and / or a second step or stepless adjustment means may be provided, with which the nominal current value and the dependence of the response time can be set separately from each other.
  • the device can be adapted to all possible applications and in particular can be set on site during assembly. For example, high rated current values with fast response can be set as well as low rated current values with slow response, and one and the same device can be used for this purpose.

  • This basic setting can be activated by an intended means, for example by a button provided for this purpose or by an optionally also latchable end or intermediate position of the adjustment.
  • the devices can be delivered to the factory and adapted only when needed and especially on site during assembly by pressing the adjustment to the local conditions, in particular to be connected consumers.
  • these can be set back from the surrounding housing and / or be actuated only with a tool. It is also contemplated to provide removable and possibly captive associated with the housing covers for the adjustment. As a further alternative, it is possible to provide a type of seal on the adjustment means which is damaged or destroyed during the first actuation, for example a web formed integrally with the housing of the device, which breaks off when the adjustment means is actuated for the first time. As a result, it would be detectable in a possible event of damage that the device was operated at least temporarily with settings changed in relation to the basic setting.

In many applications, however, the power or energy consumption to the consumer is crucial, whereas very short-term peak currents can be tolerated. In order to provide a suitable tripping characteristic for these applications, it may be advantageous to detect the integral of the current i (t) over time or else the integral of the current i (t) squared over time, at least in parallel with the assessment of the flowing current or to calculate and take into account in the tripping behavior.

  • the connection is made and can also be solved if necessary, so that the device can be made free of stress even when installed. This is particularly advantageous during assembly or in the case of an exchange of the device, because the neighboring devices do not have to be uninstalled.
