Foreword

GB/T 37751 "Residual current operated circuit breakers for household and similar purposes" is divided into the following sections. --- Part 1. Overview of independent modules and unit modules for residual current electrical standards (GB/T 37751.1); --- Part 2. Residual current electrical appliances (RCD) vocabulary (GB/T 37751.2); --- Part 3-1. Particular requirements for RCDs with non-threaded terminals to be connected to external copper conductors (GB/T 37751.31); --- Part 3-2. Particular requirements for RCDs with flat quick-connect ends (GB/T 37751.32); ---Part 3-3. Threaded terminal blocks with external untreated aluminium conductors and aluminium threaded connection to copper or aluminium conductors Special requirements for type terminal block RCD (GB/T 37751.33). This part is part 3-3 of GB/T 37751. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This section uses the translation method equivalent to IEC 62873-3-3.2016 "Residual current operated circuit breakers for household and similar purposes" Part 3-3. Threaded terminal blocks with external untreated aluminum conductors and aluminium threaded terminals with copper or aluminium conductors Special requirements for sub-RCD. The documents of our country that have a consistent correspondence with the international documents referenced in this part are as follows. ---GB/T 16916.1-2014 Residual current operated circuit breaker (RCCB) without overcurrent protection for household and similar purposes Part 1.

1 Scope

This part of GB/T 37751 applies to threaded terminals with untreated aluminum conductors or aluminium with copper or aluminium conductors. The RCD of the threaded terminal block. Threaded terminal blocks for connecting untreated aluminum conductors are made of copper or contain at least 58% Made of copper (cold worked) or copper alloy containing at least 50% copper (other processed), or with corrosion resistance not lower than copper and with suitable machine Mechanical properties of other metals or coated metals. This part cannot be used alone and must be used in conjunction with the RCD product standard (IEC 61008-1 or IEC 61009-1) for external connection. Threaded terminal block for untreated aluminum wire and aluminum threaded terminal block for connecting copper or aluminum wire. In this section, copper-plated, nickel-plated aluminum conductors are considered aluminum conductors.
