DIN rail

A mounting rail is a rail made ​​of metal. Carrier rails are used in electrical engineering for the attachment of components in junction boxes, control cabinets, junction boxes and the like. On a different rail electrical equipment can be (for example, relays, impulse relays, switches, circuit breakers, terminal blocks ) pushed laterally or plugged from the front and locked. The assembly of control cabinets and control boxes is facilitated by this standardized method for which labor costs are reduced. The various rail types are specified in DIN EN 60715 summarized standardized. This replaces the standards DIN EN 50022 ... 50024, DIN EN 50035 and DIN EN 50045.

As the material of steel, copper or aluminum is used. Mounting rails made ​​of copper or aluminum can ( PE conductor ) or PEN conductors are used in addition to the supporting function as a protective conductor; Although steel may be used as PE bar, but because of the poorer electrical conductivity is not as PEN bar.

DIN rail

A DIN rail ( TS 35) is a rail with a U-shaped or hat -like profile. In English, the rail is usually referred to as a DIN Rail; so that in particular, the 35-mm × 7.5 -mm version only, the average in the following figure.

On the top-hat rail mounting the devices are backed with a clamping mechanism. Also with regard to the size of the cabinet are standardized specifications comply, the dimensions substantially from the specific shape of the front panels of conventional distributor ( electrical installation) result, which at its rear wall rails. The width follows a designated as a division unit height of 17.5 mm. The depth of the enclosure must be at least 70 mm ( order from the rail to the front cover of the distributor to reach ), the front has a height of 45 mm (corresponding to the height of the opening slot in front panel ), this height on the first 26 mm in the depth direction must not be exceeded. The height of the rail is max. 85 mm.

G- rail

A G- rail ( TS 32 ) is a rail with G- shaped profile.
