It works in conjunction with a compatible Schneider Electric Type A toroid or rectangular sensor to measure residual earth-leakage current, tripping an associated circuit breaker when the set threshold is exceeded. The relay offers a wide sensitivity range of 0.03\u201330 A with 9 selectable thresholds and a time delay adjustable from instantaneous to 4.5 s in 9 steps. It operates on a 220\u2013240 V AC 50\/60 Hz supply and provides 1 NO + 1 NC + 1 C\/O output contacts. The unit mounts on a 35 mm DIN rail inside a switchboard, features IP40 front protection, and requires a local manual reset after fault clearance. Typical applications include protection against direct and indirect contact, fire hazards, and motor earth faults in industrial, commercial, and infrastructure power distribution systems.<\/p>\n<h2>Standardfunktionen<\/h2>\n<ul>\n<li><strong>Wide Sensitivity Range 0.03\u201330 A:<\/strong> Nine selectable residual current thresholds from 30 mA to 30 A allow precise adaptation to different protection requirements, from personnel safety to fire hazard prevention.<\/li>\n<li><strong>Adjustable Time Delay 0\u20134.5 s:<\/strong> Nine selectable delay settings from instantaneous to 4.5 s enable selective coordination with upstream and downstream protective devices.<\/li>\n<li><strong>Manual Reset with Local Control:<\/strong> The relay requires a local manual reset after fault clearance, ensuring the cause of the fault is investigated before re-energization.<\/li>\n<li><strong>Continuous Monitoring:<\/strong> The relay continuously monitors the power supply, the relay-to-toroid link, and internal electronics, providing early detection of system faults.<\/li>\n<li><strong>ComPacT Circuit Breaker Coordination:<\/strong> Ensures coordination with ComPacT circuit breakers, switching off within 40 ms for fast and reliable fault disconnection.<\/li>\n<li><strong>Type A Residual Current Detection:<\/strong> Works with Schneider Electric Type A toroids or rectangular sensors to detect AC and pulsating DC residual currents.<\/li>\n<li><strong>Reinforced Insulation (Overvoltage Category IV):<\/strong> VigiPacT relays feature reinforced insulation rated for overvoltage category IV, suitable for installation at the origin of the electrical supply.<\/li>\n<\/ul>\n<h2>Technische Spezifikationen<\/h2>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Wert<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Hersteller<\/td>\n<td>Schneider Electric<\/td>\n<\/tr>\n<tr>\n<td>Modell<\/td>\n<td>56173<\/td>\n<\/tr>\n<tr>\n<td>Serie<\/td>\n<td>VigiPacT<\/td>\n<\/tr>\n<tr>\n<td>Kurzname des Ger\u00e4ts<\/td>\n<td>RH99M<\/td>\n<\/tr>\n<tr>\n<td>Produkttyp<\/td>\n<td>Residual Current Protection Relay (Earth-Leakage Relay)<\/td>\n<\/tr>\n<tr>\n<td>Nennversorgungsspannung<\/td>\n<td>220\u2013240 V AC, 50\/60 Hz<\/td>\n<\/tr>\n<tr>\n<td>Reststromempfindlichkeit<\/td>\n<td>0.03\u201330 A (9 selectable thresholds)<\/td>\n<\/tr>\n<tr>\n<td>Time Delay<\/td>\n<td>0\u20134.5 s (9 selectable settings)<\/td>\n<\/tr>\n<tr>\n<td>Output Contacts<\/td>\n<td>1 NO + 1 NC + 1 C\/O<\/td>\n<\/tr>\n<tr>\n<td>Nennsto\u00dfspannungsfestigkeit (Uimp)<\/td>\n<td>8 kV<\/td>\n<\/tr>\n<tr>\n<td>Monitored System Voltage<\/td>\n<td>Up to 1000 V AC, 50\/60\/400 Hz<\/td>\n<\/tr>\n<tr>\n<td>Montage<\/td>\n<td>DIN-Schiene (35 mm)<\/td>\n<\/tr>\n<tr>\n<td>Schutzart<\/td>\n<td>IP40 (front face)<\/td>\n<\/tr>\n<tr>\n<td>Abmessungen (B \u00d7 H \u00d7 T)<\/td>\n<td>54 mm \u00d7 97 mm \u00d7 74 mm<\/td>\n<\/tr>\n<tr>\n<td>Nettogewicht<\/td>\n<td>0.276 kg<\/td>\n<\/tr>\n<tr>\n<td>Normen<\/td>\n<td>IEC 60947-2;
