IEC 60947-7-4:2013 PDF (Not Available)

IEC 60947-7-4:2013 provides guidelines for the design, construction, and performance of PCB terminal blocks used in low-voltage switchgear and controlgear applications. These terminal blocks are designed to securely connect copper conductors to a printed circuit board through various methods such as soldering or press-in techniques.

The standard specifies that these terminal blocks can accommodate copper conductors with cross-sections ranging from 0.05 mm² to 300 mm² (AWG 30/600 kcmil) and can be used in circuits with a rated voltage not exceeding 1,000 V AC up to 1,000 Hz or 1,500 V DC.

The purpose of this standard is to ensure the safe and reliable functioning of PCB terminal blocks, protecting against issues such as poor electrical connections, mechanical failure, or insulation breakdown. Compliance with IEC 60947-7-4:2013 helps to guarantee the proper installation and operation of these terminal blocks in industrial or similar applications.
