Application Summary AI generated

This standard specifies the performance requirements, test methods, and safety criteria for PCB terminal blocks designed to connect copper conductors in low-voltage switchgear and controlgear assemblies. It is applied in industrial electrical equipment, control panels, and distribution systems where reliable, solderless wire-to-board connections are needed for auxiliary circuits. Manufacturers and testing laboratories use this standard to verify mechanical and electrical endurance, temperature rise limits, and secure clamping of copper wires in printed circuit board applications.
