Residual current operated circuit breakers for household and similar purposes
Part 3-2. Flat end with flat connection
Special requirements for RCD
1 Scope
This part of GB/T 37751 applies to RCD with flat quick-connect tip, which has a nominal width of 6.3 mm and thickness.
0.8mm plug-in connector (see 3.2) and its associated plug connector for connecting the electrical copper guide according to the manufacturer's instructions
Line, rated current is less than or equal to 16A.
This part cannot be used alone. It must be used together with the RCD product standard (IEC 61008-1 or IEC 61009-1) for flat quick connection.
Connect the end of the RCD.
The connectable electrical copper wire is a flexible wire with a cross-sectional area of 4 mm 2 or less, or a hard wire with a cross-sectional area of 2.5 mm 2 or less (AWG
The wire gauge is equal to or greater than 12).
This section specifically applies to the RCD of the plug-in tab as an integral part.
