This document is modified to adopt IEC 61535:2023 "Mounted couplers for permanent connections in fixed installations".

The technical differences between this document and IEC 61535:2023 and their reasons are as follows.

--- Added "This document specifies the classification, marking and documents, dimensions, structure and (see Chapter 1) to meet the requirements of GB/T 1.1-2020;

--- Added "After this test, the mark should still be clearly visible" (see 8.3) in the marking test to adapt to my country's technical conditions and increase the Operability;

--- Replaced IEC 60998-2-3 (see 11.1.2) with the normative reference GB/T 13140.4 to adapt to my country's technical conditions and added Operability;

--- The normative reference GB/T 4207 replaces IEC 60112 (see Chapter 24) to adapt to my country's technical conditions and increase operability Sex;

--- Replaced IEC 60695-2-11 (see 24.1) with the normative reference GB/T 5169.11 to adapt to my country's technical conditions, and added Operability.

The following editorial changes were made to this document.

---Replaced IEC 60417:2006 with the informative reference GB/T 5465.1-2009 to adapt to my country's technical conditions and increase the Operability;

---Replace IEC 60309 (all parts) with the informative reference GB/T 11918 (all parts) to adapt to my country's technical requirements parts, increasing operability;

---Replaced IEC 60320 (all parts) with the informative reference GB/T 17465 (all parts) to adapt to my country's technical requirements parts, increasing operability;

---Replaced IEC 61995 (all parts) with the informative reference GB/T 31463 (all parts) to adapt to my country's technical requirements parts, increasing operability;

---Replace IEC 60364 (all parts) with the informative reference GB/T 16895 (all parts) to adapt to my country's technical requirements parts, increasing operability;

--- Adjust the order of the appendices according to the order in which they appear in the main text to adapt to my country's technical conditions and increase operability;

--- Deleted the notes in Chapter 4 and 5.1 to adapt to my country's technical conditions and increase operability.

1 Scope

This document specifies the classification, marking and documentation, dimensions, construction, mechanical properties, Technical requirements such as electrical performance and thermal performance.

This document applies to two-wire to five-wire mounting couplers with or without grounding, with a rated voltage not exceeding 500VAC or DC, rated the rated connection capacity does not exceed 10mm2 and the rated current does not exceed 32A. It is used for permanent connection of electrical devices. In addition to the power supply voltage, there are additional Mounted couplers with contact voltage are outside the scope of this document.

In this document, a mounting coupler consists of a female connector and a male connector for permanent connection.

The clutch is not intended to be connected or disconnected under load, nor is it intended for use except for initial installation and reconfiguration or repair after installation.

This means that the mounted coupler is designed for infrequent connection and disconnection operations.

Mounted couplers are not suitable for socket systems or for lighting connection devices that comply with GB/T 31463 (all parts).

(DCL), and lamp support coupler (LSC).

Mounting couplers that meet the requirements of this document are suitable for use in indoor and outdoor locations where the ambient air temperature does not normally exceed the upper limit the temperature should be 40°C and not exceed 35°C on average within 24h, with the lower limit being -5°C.

NOTE 1 Additional tests for use in cold climates are given in Annex A. The necessary information is given in the manufacturer's installation instructions.

NOTE 2 For other temperatures, the necessary information is given in the manufacturer's installation instructions.

In places with special conditions, such as on ships, vehicles and similar places, as well as dangerous places, such as places where explosions are likely to occur, special Special structure.

Note 3.The installation coupler must be installed by trained or professional personnel.

Note 4.See Appendix B for guidance on the use of mounted coupler systems.
