17、Two types of rails are specified in European Standard EN 50022, top hat rails, 35 mm wide for the snap-on mounting of equipment. For equipment which is either too large or too heavy for either of the 35 mm rails, a 75 mm wide top hat rail is specified in European Standard EN 50023, for snap-on mount
18、ing of equipment. For the mounting of equipment by means of screws, C profile rails are specified in European Standard EN 50024. In European Standard EN 50035 a G profile rail is specified, which is still widely used, and especially intended for snap-on mounting or screw fixing of terminal blocks. T
19、his European Standard specifies requirements for top hat rails, which are especially intended for snap-on mounting of terminal blocks. 2 Scope This European Standard specifies requirements for one size of top hat steel rails for the fixing of terminal blocks. 3 Dimensions Dimensions of top hat rails
20、 are shown in Figure 1. The dimensions shall apply over the whole length of the top hat rail, verification of these dimensions shall not be made less than 10 mm from each end. 4 Designation The designation of a top hat rail, 15 mm wide and 5 mm high shall be as follows: Top hat rail EN 50045 15 5. 5
21、 Material The material used shall be cold rolled carbon steel sheet, and have the following characteristics: skin passed after annealing, bright surface finish, with a tensile strength between 320 N/mm2 and 420 N/mm2 elongation at least 30 % 180 bend test horizontally and transversally with regard t
