A fuse monitoring device for monitoring a fuse supported by a fuse block, the fuse monitoring device including a housing. The housing includes a holder attachment mechanism configured to connect the fuse monitoring device to a fuse block. The housing also includes a mounting attachment mechanism configured to connect the fuse monitoring device to a mounting structure and at least one sensor configured to be operably connected to a fuse and configured to measure fuse data associated with the fuse. The monitoring device further includes at least one processor communicatively coupled to the at least one sensor.

A pattern fuse includes a lower film layer, an adhesive layer stacked on the lower film layer, a circuit pattern made of a conductive material and provided on the adhesive layer, an upper film layer stacked on the adhesive layer and the circuit pattern and a coating layer configured to cover the opening of the upper film layer, wherein the coating layer includes a flame retardant material. The upper film layer has an opening formed therein that is configured to allow a part or the entirety of the circuit pattern to be exposed therethrough. A method of manufacturing the pattern fuse is also provided.

For providing data of an apparatus for applications, routing of the data via a communication node is provided. In this case, the apparatus communicates the data wirelessly to the communication node. This necessitates pairing the apparatus with the communication node beforehand, which is carried out with the aid of an installation key. The data transfer itself is then secured with a connection key defined during the pairing. If replacing or reconnecting the communication node necessitates carrying out re-pairing, at least one criterion relating to the reachability of the communication node is checked and the lack of reachability as per the criterion is made into the prerequisite for using the installation key instead of the connection key for re-pairing. At least one embodiment of the invention increases protection against interferers wanting to access the apparatus in an unauthorized manner.

An arc suppressing circuit configured to suppress arcing across a power contactor coupled to an alternating current (AC) power source having a predetermined number of phases, each contact of the power contactor corresponding to one of the predetermined number of phases includes a number of dual unidirectional arc suppressors equal to the predetermined number of phases of the AC power source. Each dual unidirectional arc suppressor includes a first phase-specific arc suppressor configured to suppress arcing across the associated contacts in a positive domain, a a second phase-specific arc suppressor configured to suppress arcing across the associated contacts in a negative domain, and a coil lock controller, configured to be coupled between a contact coil driver of the power contactor, configured to detect an output condition from the contact coil driver and inhibit operation of the first and second phase-specific arc suppressors over a predetermined time.

An electronic assembly contains a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point and a contact clip bridging the interruption point. The contact clip is manufactured without a preload, as a thermal fuse. The contact clip has a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder. The contact clip further has a fixing limb with a limb end seated in a circuit board opening. The limb end of the fixing limb is oversized relative to a circuit board opening, and a deformation being imparted to the contact clip, with an internal preload being generated.

A high speed arc suppressor and method include a first phase-specific arc suppressor configured to suppress arcing across contacts of the power contactor in a positive domain and a second phase-specific arc suppressor configured to suppress arcing across the contacts in a negative domain. First and second high speed switches are configured to enable and disable operation of an associated one of the first and second phase-specific arc suppressors. First and second drivers are configured to drive the first and second high speed switches.

A sliding power contact and method includes a mobile load device connector and a socket. The mobile load device connector includes a non-current power pin having a first length, a current power pin having a second length less than the first length, a neutral pin, and a ground pin. The socket includes a non-current power contact configured to electrically couple with the non-current power pin, a current power contact configured to electrically couple with the current power pin, a neutral contact configured to electrically couple with the neutral pin, and a ground pin configured to electrically couple with the ground pin. An arc suppressor is directly coupled to at least one of the non-current power pin and the non-current power contact, wherein the arc suppressor, the non-current power pin and the non-current power contact form a current path between the current power pin and the current power contact.

The invention relates to a conducting track fuse (1) for an electrical or electronic device, comprising: a first and a second connection region (2a, 2b); a nonlinearly extending burn-out region (3), which is arranged between the first and second connection regions (2a, 2b); and a covering element (15), which has at least two side walls (9) and a covering face (8), which covering element is arranged over the first and second connection regions (2a, 2b) and over the burn-out region (3), the burn-out region (3) and the covering element (5) being arranged relative to each other in such a way that the area of the covering face (8) covers the burn-out region (3) and a cavity (7) is formed between the burn-out region (3) and the covering face (8) as a result of the height of the side walls (9).
