Busbars for Arc Fault Detection Devices
Since December 2017, the use of a fire circuit breaker in the construction of new plants or the expansion or modification of existing systems, according to DIN VDE 0100-420: 2016-02 is no longer mandatory, but should be taken for granted. Electricity is one of the most common causes of fire, caused by damaged cable insulation, crushed wires, kinked plugs, loose contact points or faulty terminals.
Therefore, the use of fire protection switches, “Arc Fault Detection Devices” (AFDD) is recommended for low-voltage systems. These protect against the occurrence of dangerous, serial or parallel fault arcs in single-phase AC systems with currents up to 16A.
Everyone should therefore contribute to the safety of persons, capital goods and to prevent fires and in these applications retrofit AFDD circuit breakers made of halogen-free material.
Already years ago there has been a connection between electrical engineering and art. It was an art to manage the wiring safety devices in switchboards without any errors.
Conventionally, busbars for one to four pole wirings have been developed over the years which electrician can cut individually into the right length.
For, more efficiency FTG has developed the Eurovario busbar. This is a compact system which is prefabricated in Triberg. The ready-to-use busbars are available in various versions. At the beginning the main intention was to create a compact, a clear and a beneficial busbar which is fast to install and takes a less storage space. The main advantage of the busbar, a simple connection, will be quickly realizable for electricians if circuits are to add like is usually in domestic installations. Even with a small selection of busbars in stock a wide range of connection can be made in no time without complex dismantling of the old busbar and without sawing and burring.
The temporary solution for confined spaces
Space in the distribution cabinet is expensive. Space is often left between the mounting plate and the top hat rail when devices are installed on DIN rails some distance apart. But if there is no space left for additional fuse devices on the right, devices often have to be accommodated in the next one. This requires space behind the devices or on the side so that the next row can be wired.
The sparse amount of space available is used efficiently by onward connection using row connectors. The row connectors can run at the side or behind the devices and therefore save on assembly space.
Row connectors are available completely sealed or overmoulded, in 4-pole version, different colours or with a reduced distance from the mounting plate. The row connectors are prefabricated to suit customer requirements.
