Overview

IEC 61076-3-118:2010 specifies detailed product requirements for rectangular power connectors with 4 poles plus a protective earth (PE) contact. This standard is published by the International Electrotechnical Commission (IEC) and targets connectors used in industrial electronic equipment. The connectors feature a push-pull coupling mechanism, designed to ensure secure and reliable connections while facilitating quick mating and unmating. Protection ratings of IP65 and IP67 are achieved, making these connectors suitable for harsh environments with dust and water exposure.

Designed specifically for industrial applications, the standard covers both fixed (male) and free (female) connector versions. These connectors use round contacts and support termination by screw or crimp methods, with other termination techniques like soldering or printed board connections available upon agreement between manufacturer and user. Notably, these connectors do not have a breaking capacity rating under IEC 61984, indicating they are generally not intended to be connected or disconnected under load unless specified otherwise by the manufacturer.

Key Topics

5.2 Test schedules
5.2.1 Basic (minimum) test schedule
Not applicable.
5.2.2 Full test schedule
Contact resistance measurements and contact disturbance measurements may be performed
on different contacts. It is permissible to prepare separate connectors for each.
Dimensions shall be measured that affect clearance and creepage distances and other
critical dimensions that affect intermateability.
The test parameters required shall not be less than those listed. The following tests specify
the minimal characteristics to be checked and the minimal requirements to be fulfilled. The
test results shall be written down in a test report.
In Table 7 below, the minimum number of contacts shall be satisfied; for example if a
connector has only 4 contacts, there shall be 4 connectors for test group AP, to satisfy the
minimum number of contacts under test.
As only one performance level exists, the tests do not differ depending on performance level.
