Type number key for portable power distribution centres
1. Designation according to El-Björn system, see explanation below.
Obligatory space.
2. Rated current in Amperes.
3. Additional designation indicating version or enclosure type.
4. Rated voltage, refers to mains voltage/system voltage/between phases in Volts. Normally not included for 400V. Transformer specified by primary and secondary voltage(s), separated by - (e.g. 400-230-48 indicates 400V in and 230V and 48V out). If rated voltage is included, it must be preceded by a space.
Obligatory forward slash.
5. * Number of fixed outlets ≤125A.
6. * Number of fixed outlets >125A.
Obligatory forward slash.
Group 7–10 should be preceded by a parenthesis unless it is empty.
7. * Number of sockets of type CEE 1-phase 16A
8. * Number of sockets of type CEE 1-phase 32A
9. * Number of sockets of type CEE 1-phase 63A
10. * Number of sockets of type CEE 1-phase 125A
Group 7–10 should be followed by a parenthesis unless it is empty.
11. * Number of Schuko-type sockets.
12. * Number of sockets of type CEE 3-phase 16A.
13. * Number of sockets of type CEE 3-phase 32A.
14. * Number of sockets of type CEE 3-phase 63A.
15. * Number of sockets of type CEE 3-phase 125A.
Group 16–19 should be preceded by a hyphen unless it is empty
16. * Number of residual current devices ≤30mA.
17. * Number of residual current devices >300mA.
18. * Number of residual current devices >30mA & ≤300mA.
19. * Number of residual current devices/earth fault relays with variable setting.
20. Connection standard, EN indicates that all sockets ≤32A are protected by a 30mA residual current device. Preceded by a space unless it is empty.
21. Possible additional text describing assembly, see explanation below.
22. Country version, indicates which country the product is intended for in terms of language, stickers, drawings and national standards, e.g. metering centres and Schuko-type sockets. Please note that apart from the language on stickers etc., it may be possible to use the centre in other countries too! If the item is completely universal in terms of design and language on stickers/instructions etc., the country version is omitted. May be combined with several language designations. If so, there is no space between language designations (e.g. SEFI). Standardized country codes are used, in accordance with ISO 3166-1, see examples below. Preceded by a space unless it is empty.
System El-Björn
1. System El-Björn (based on SS-EN 61 439-4)
U Outlet socket centre
Construction site assembly with a single plug-type input and outlet(s) consisting of sockets for plugs.
SF Final power distribution centre
Construction site assembly with input for direct cable connection and outlet(s) consisting of sockets for plugs.
F Power distribution centre
Construction site assembly with input for direct cable connection and outlet(s) for direct cable connection.
Z Supply and metering centre
Construction site assembly with input and metering device.
If no supplementary designation is given, the product has an output for direct cable connection.
T Transformer centre
Construction site assembly with input and transformer.
UF Outlet socket centre for permanent installation
Assembly with input for direct cable connection and output(s) consisting of direct cable connections and/or sockets for plugs.
Alfa-II Marina/Camping power pillar
Pillar with input for direct cable connection and output(s) consisting of direct cable connections and/or sockets for plugs.
The various assembly types can be combined, e.g. FSF, ZF, ZFSF, TU, TUF.
The most commonly used supplementary information is the rated current or enclosure
type of the assembly. If no supplementary designation is given, the product has an output unit.
3. Enclosure variants
BCS Modular construction site assembly. If there is a letter E in front it
indicates that the input has a circuit breaker, and if the letters GE are
in front it indicates a wall-mounted assembly with input circuit
breaker (usually on mains distribution assemblies rated at 400A–800A).
