With an 80 mm inner diameter and a rated operational current of 160 A, it is compatible with VigiPacT RH10M to RH197P relays and Vigilohm insulation fault locators. The transformer ratio of 1\/1000 enables precise measurement of residual currents for reliable fault detection. It withstands a rated short-time current of 85 kA for 0.5 seconds and features reinforced insulation with an overvoltage category IV rating. The toroid is suitable for fixed mounting on cables, backplates, or DIN rail, and operates reliably from -35 \u00b0C to +70 \u00b0C in industrial and commercial power distribution systems.<\/p>\n<h2>Recursos padr\u00e3o<\/h2>\n<ul>\n<li><strong>Type A Residual Current Sensing:<\/strong> Detects AC and pulsating DC residual currents for comprehensive earth leakage protection in
