Translation of "Elektrischer schutz" in English

Thermik provides powerful solutions to protect electrical equipment from overheating.

So-called electrical protective devices are normally used for monitoring and for protection of electrical power supply systems.

For protection of electrical equipment such as transformer, composite apparatus is more reliable than circuit breaker.

The use of substrate diodes is a proven way to protect electric conductors against transient negative high voltages.

Furthermore, electric bumper protection and an LED light for enhanced visibility during the night can also be included.

One such overvoltage protection means is used to protect electrical circuits or systems or devices.

Electric automation devices are used, for example, to control, monitor and protect power grids.

An IP rating describes levels of protection for electrical equipment against solids and liquids.

The product is not considered to be an insulating fitting for electrical appliances of heading 8547 as it is not specifically designed for insulating purposes but for protecting the electrical connections.

The object of the present invention is to build a casing of the kind described above but which is particularly suitable to the protection of an active component such as a surface-wave filter-chip.

Moreover, additional protection, both mechanical and electrical, is provided by the fact that it is not possible to push a narrow object through the slot and inside the mechanism.

The conductor body 1, the support body 2, the coupling nut 16, the spring rings 4 and 4.1, and the housing of another connector not shown, but matching with the connector 18, are all made of electrically conducting material to become part of a grounding circuit for protecting electrical installations in an aircraft against electro-magnetic disturbances such as excess voltages and excess currents caused, for example, by lightning.

Such temperature controllers are used to protect electrical consumers, for which purpose they are connected in series with the consumer so that the consumer's operating current flows through the temperature controller.

The present invention is directed to an arrangement for protecting electrical installations against electromagnetic disturbances, especially against overvoltages and lightning strikes, and involve a braiding consisting of an electrically conducting material which embraces electrical wiring lines laid in bundles between individual electrical equipment and which is connected conductively by connector elements with charge eliminator points.

The invention is directed to an arrangement for protecting electrical installations against electromagnetic disturbances, especially against excess voltages and the effects of lightning, which arrangement uses metallic shielding which embraces the electrical lines laid between individual electrical apparatus and which is in electrical connection with charge eliminator points.

Depending on the location, whether in subway stations, airports or simply in an urban environment, our solutions cope with the prevailing influences such as wind loads, moisture or electrical protection with backlit signs.

Pforzheim loses a figurehead: The company Thermik is considered a global market leader in the development and production of thermal protectors for preventing overheating of electrical devices.

In order to avoid these disadvantages, it is also known to apply coatings for the protection of electrical cables which becomes intumescent with thermal impact in the event of fire, i.e. they foam and thus form an insulation layer or they receive heat due to physical and chemical processes and thus act in a cooling manner.

DE 198 22 056 A1 discloses a temperature protection circuit for protecting electrical devices having a series connection of PTC thermistors having stepped nominal response temperatures.

Embodiments of the invention are not restricted to the protection of electrical switches with a rotary contact system but can also be used for other types of switch.

Circuit arrangements for storing the phase of an a-c voltage are employed, among other things, in equipment for the protection of electric power transmission lines. For instance, such storage is used where it is necessary to reliably determine the direction of the location of a short circuit as seen from the place of installation of the equipment.

An example of an automation system is a substation automation system for controlling, monitoring and protecting electrical power grids and substations.

The power tool as claimed in claim 1, wherein at least one radially inwardly offset shading rib, for protecting electrical components, is disposed on the inside of the housing cover, which shading rib is configured to be brought into engagement with an associated recess on the motor housing.

From US 2005/0057336 A1, a thermally actuated circuit breaker for protecting electrical components against excess current, having a switch housing and a temperature-dependent switching mechanism disposed therein, is known, which produces as a function of its temperature an electrically conductive connection between two external terminals leading out of the switch housing, which are fed out on opposite sides of the housing.

This has the particular advantage that a circuit breaker is extended to include a further advantageous functionality for the protection of electrical systems.

According to another advantageous embodiment, at least one radially inwardly offset shading rib, for protecting electrical components, is disposed on the inside of the housing cover, which shading rib is for bringing into engagement with an associated recess on the motor housing.
