Abstract: A fuse element for a fuse with an integrated measurement function, includes a first receiving area in an embodiment, for receiving a melting conductor of the fuse, delimited in the length direction of the fuse by a closure element and in a direction orthogonal to the length direction by the fuse element. Further, in an embodiment, the fuse element has a second receiving area, physically separated from the first receiving area, for receiving a measuring device of the fuse. The second receiving area is designed to receive the measuring device in a wall section of the fuse element. The second receiving area formed in the fuse element protects the measuring device arranged therein against interfering environmental influences. The measuring device is used to ascertain the electric current flowing through the fuse directly on the fuse.

Abstract: A fuse includes an integrated measuring function. In an embodiment, the fuse includes a fuse housing which in turn has a first receiving space delimited by a pressure body and a second receiving space which is spatially separated from the first receiving space and is delimited by a protective body, the first and second receiving spaces being arranged one behind the other in a direction of longitudinal extent. A fusible conductor is accommodated and mounted in the first receiving space and a measuring device is accommodated and mounted in the second receiving space. The measuring device has a current transformer and an electronic assembly which is electrically conductively connected to the current transformer. The current transformer and the electronic assembly are arranged one behind the other in the direction of longitudinal extent.

A fusible conductor is mounted in the first receiving space and a measuring device is accommodated and mounted in the second receiving space. The measuring device has a current transformer and an electronic assembly, electrically conductively connected to the current transformer. Viewed in a direction of longitudinal extent, a height of the current transformer essentially corresponds to a height of the second receiving space. With the aid of the measuring device, it is possible to determine the electric current flowing through the fuse in the immediate vicinity of the fuse. Energy required is generated from the primary current of the fuse by electromagnetic induction, meaning no external power source is required.

Abstract: An arrangement includes a conductor, forming the primary side of a transformer, the secondary side being connected to a rectifier circuit. The rectifier output is connected to a voltage stabilizing circuit for an electronic unit and to a first series circuit formed by a first switching component and a first resistor. In the event of a first voltage value being reached at the first input of the voltage stabilizing circuit, the first switching component is switched to be conductive. The secondary current of the transformer flows via the first resistor to drop an electrical voltage across the first resistor. The electric current of conductor is determinable from the voltage. The use of just one transformer used both for energy generation and for current measurement makes it possible to realize a very compact and small design of a current measuring device having a simple construction.

Abstract: A current sensor is for determining the level of the current of a conductor of a low-voltage circuit. In an embodiment, it includes a current transformer including a magnetic core. The magnetic core is an annular core having a core inner diameter, a middle diameter and a core outer diameter. The annular core is wound with a secondary winding, including an inner opening with an inner diameter and an outer circumference with an outer diameter. The secondary winding supplies the circuit with electrical energy. The wound annular core is configured such that the difference between the middle diameter as the minuend and the inner diameter as the subtrahend is 0.5 to 0.6 times smaller than the difference between the outer diameter as the minuend and the inner diameter as the subtrahend, to achieve an optimum for supplying energy and determining the level of the current in connection with the circuit.

Abstract: An arrangement is for determining the level of the electric current for a low-voltage circuit. The arrangement includes a conductor, forming the primary side of a transformer, the secondary side being connected to a rectifier circuit. A first output of the rectifier is connected firstly via a first diode to a voltage stabilizing circuit for an electronic unit having a controller and secondly to a first series circuit formed by a first switching component and a first resistor. The arrangement is configured in such a way that in the event of a first voltage value being reached at the first input of the voltage stabilizing circuit, the first switching component is switched to be conductive. The secondary current of the transformer flows via the first resistor, as a result of which an electrical voltage is dropped across the first resistor. The electric current of conductor is determinable from the voltage.
