Marine 16~125A plugs, socket-outlets and couplers
1 Subject content and scope of application
GB12321-90
This standard specifies the classification, technical requirements, test methods and inspection rules for marine 16~125A plugs, socket-outlets and couplers. This standard applies to plugs, sockets and connectors with an AC voltage of 50Hz or 60Hz, a rated voltage not exceeding 440V or a DC rated voltage not exceeding 220V, and a rated current of 16 to 125A, used in general ships, refrigerated containers and docks. However, it is not applicable to places with explosion hazards.

It refers to a mechanical structure that prevents the plug pin from being energized before the plug and socket or connector are plugged in, and can also prevent the plug pin from being pulled out when energized.
3.2 Retention device
It refers to a mechanical structure that keeps the plug or connector in the normal working position when it is plugged in to prevent accidental disengagement. 4 Product classification
4.1 See Table 1 for basic parameters.

Grounding contact
Clock position
Note: ① The position of the grounding contact is determined by comparing the front of the socket with the clock face, setting the key slot position at 6 o'clock (6h), and then according to the clock position of the grounding socket, see Appendix A (supplement). 250V or 440V is only for refrigerated containers. 4.2

Note: 1) Within the distance specified by ts, d and L should be within the limit. If ts is exceeded, d and L can be greater than the specified value. 2) The dimensions of the socket d and d do not have to be circular, which is related to the pin. 3) For the socket with 3P+N++10 poles, the value of dimension h for the neutral line socket is 16.0mm. 4.4 The construction and dimensions of 16A and 32A plugs and connector plugs are shown in Figure 4 and Table 3.
