Embodiment Construction

[0030] exist figure 1 shows a protective device SCH with a plurality of protective elements E1 . . . En. In this case, initially three protective elements E1, E2, E3 are combined to form a first protective device block B11 and the remaining protective elements E4...En are combined to form a second protective device block B12. The first load or load branch V1 is connected to the supply voltage U of the power supply via the first protective device block B11 and the second load or load branch V2 is connected to the supply voltage U of the power supply via the second protective device block B12.

[0031]Each protection element El...En includes a current limiting element Tl...Tn and a current detection unit I1...In. The corresponding current-limiting elements T1 . . . Tn are designed, for example, as transistors and the corresponding current detection units I1 . . . The current flow through the current-limiting elements Tl...Tn is controlled in dependence on the respective detect...

Abstract

The protection device (SCH) has current-limiting or switching-off protection elements (E1-En) including outputs, which are connected in a parallel using a connecting ridge. The connecting ridge is provided with a manually separable disconnecting point (Br), which has a disconnecting piece. A marking is provided below a disconnecting point and / or the disconnecting piece for displaying ridge separation. Chip temperature of the protection elements is detected as a critical parameter. Control units (A1-An) determine contact resistances of current limiting elements (T1-Tn). An independent claim is also included for a control method of an electrical protection device.

Description

technical field [0001] The invention relates to an electrical protective device for being arranged between at least one load and a power source, wherein the protective device has a current limiting function and a disconnection function with an adjustable current limit value. Furthermore, the invention relates to a control method of an electrical protection device. Background technique [0002] Electrical protective devices are used everywhere where interference situations in electrical installations can lead to hazards for people and / or machines. Electrical protective devices are required in particular when a load or loads are supplied by means of a power supply. The electrical protective device is arranged between a power source and one or more loads in order to reduce the current through the one or more loads in the event of a disturbance and to open the circuit in the event of a persistent disturbance. [0003] For example, DE 101 49 458 C1 shows a protective device bet...
