scope:

This part of IEC 61076-2 specifies circular connectors size 15 with bayonet-locking, with up to 3 power contacts with rated insulation voltage up to 630 V AC/DC and rated current up to 20 A plus PE and up to 3 auxiliary contacts with rated insulation voltage up to 63 V AC/DC and rated current up to 10 A, that are typically used for industrial power supply and power applications as asynchronous motors. These connectors consist of both, fixed and free connectors either rewireable or non- rewireable, with bayonet-locking. Male connectors have round contacts Ø1,6 mm. NOTE: Size 15 is the dimension of the inner contact carrier of the male connector interface (dimension AG in Table 18).
