IEC 60906-1 Figure 1 Single-Pole Insertion Prevention Test Gauge for 16A 250V A.C. Socket-Outlets

This IEC 60906-1 Figure 1 Single-Pole Insertion Prevention Test Gauge is precision-engineered to comply with IEC 60906-1 Figure 1 standards, designed exclusively to verify the single-pole insertion prevention function of 16A 250V A.C. household and similar-purpose socket-outlets. It features a robust construction with corrosion-resistant, high-rigidity metal (e.g., stainless steel) and is calibrated to apply test force under its own weight, ensuring accurate simulation of real-world usage scenarios. Equipped with an electrical contact indicator (40V-50V), the gauge effectively confirms whether socket-outlets can prevent accidental single-pole insertion— a critical safety requirement to mitigate electric shock risks. As an essential tool for compliance testing, it supports quality assurance and certification processes for electrical accessories adhering to international safety norms.
