scope:

This part of IEC 61076 establishes specifications and test requirements for a connector with four contacts plus PE contact, for use in industrial environments. This International Standard specifies free and fixed connectors, with round contacts, suitable for screw or crimp terminations. Other terminations techniques, as solder or printed board connections are upon agreement between manufacturer and user. The free and fixed connectors have a push-pull locking mechanism for IP65 and IP67 protection according to IEC 60529. The PE contact is first-make last-break. Connectors according this International Standard are without breaking capacity COC according to IEC 61984, therefore they are not intended to be engaged or disengaged in normal use when live or under load, if not otherwise specified by the manufacturer.
