Contactor relays may be given a distinctive number and terminal marking according to the General rules, EN50005. On this basis, it is de

14、sirable to lay down more detailed rules for particular contactor relays, such as those defined in clause1.

16、, having specific relative positions of the contact elements and an associated terminal numbering sequence. These particular contactor relays are designated by a distinctive number followed by a specified distinctive letter. The use of this standard is recommended where terminal marking is a require

17、ment of the relevant standard for contactor relays, or is usual practice. 2 Terminal marking rule The contactor terminal marking of a contactor relay is formed, in principle, by two figures. 2.1 Function number. The unit number is a function number, i.e.: 1 2 for break-contacts; 3 4 for make-contact

18、s. 2.2 Sequence number. The figure of the tens is a continuous sequence number beginning with 1 (except for contactor relays designated01E), independently of the contact function. Terminals belonging to the same contact are marked with the same sequence number. For contactor relays having 10 contact

19、 elements, the sequence number 10 shall be replaced by 0. 2.3 Numbering method. The contact numbering is made, without any break, from left to right on the device; for devices with tiers, the numbering begins with the tier next to the mounting level. Example of contact numbering methods on contactor

20、 relays of various constructional types, but with the same distinctive number 62 E The prescribed numbering method does not allow blank contact cells inside a contact series. 3 Distinctive number and distinctive letter The number, type and location of contact elements of contactor relays according t

21、o this standard are indicated by a distinctive number followed by a distinctive letter. 3.1 Distinctive number. In accordance with EN 50005, clause 6, the first figure of the distinctive number gives the quantity of make-contact elements and the second figure the quantity of break-contact elements.

22、3.2 Distinctive letter. The distinctive letter indicates the location of the contact elements in relation to each other and their terminal marking. Clause 4 defines the arrangement of contactor relays indicated by the distinctive letter E. Appendix A gives information on permissible deviations, indi

23、cated by the distinctive letters X, Y or Z.EN50011 4 BSI 08-1999 For new designs, the arrangement indicated by the distinctive letter E should be preferred. 4 Contactor relays designated by the distinctive letter E For contactor relays having the same distinctive number and the distinctive letter E,

24、 independently of their construction, the sequence of the contact elements within the device is specified according to the diagrams of Table 1. According to the present rule, the sequence number becomes a location number and allows a given contact element terminal of a contactor relay in the equipme

25、nt to be quickly found solely by counting the contacts.

A.2 Contactor relays designated by the distinctive letter X If the locat

27、ion of the contact elements within the device and the terminal marking differ from the requirements of clause 4, the device is designated by the distinctive letter X instead of the distinctive letter E. Such a device shall still comply with the requirements of clauses 2 and3 of the present standard
