For certain equipment such as auxiliary contact elements of contactors and
control relays, the EN 50 012 and EN 50 011 standards also apply.
The EN 50 012 defines the terminal markings and identification numbers for
auxiliary contact elements of particular contactors.
The terminal markings of the auxiliary contact elements match the terminal
markings of corresponding control relays with the ID letter E (in acc. with
EN 50 011). For auxiliary contact elements of contactors with the same iden-
tification number, the terminal marking must correspond to the sequence
defined in the standard.
