It is self-powered from the measured voltage, accepting a nominal supply of 208\u2026440 V AC (operating range 183\u2026484 V AC) at 50\/60 Hz \u00b110%. The relay provides two changeover (2 C\/O) output contacts rated 5 A nominal current and 1250 VA maximum switching capacity. It features a maximum response time of 100 ms on fault appearance and a 500 ms pick-up delay. The 17.5 mm modular width matches a single-pole circuit breaker, simplifying panel design, while a transparent cover protects settings from tampering. Typical applications include hoisting, packaging, lifts, textile machinery, pumping, and water treatment systems requiring reliable phase monitoring[reference:0][reference:1].<\/p>\n<h2>Standard Features<\/h2>\n<ul>\n<li><strong>Phase Sequence &amp; Total Phase Loss Monitoring:<\/strong> Continuously verifies the correct L1-L2-L3 sequence and detects the total loss of one or more phases, protecting three-phase equipment from supply faults[reference:2].<\/li>\n<li><strong>Self-Powered from Measured Voltage:<\/strong> Requires no separate auxiliary supply; the relay draws its operating power directly from the monitored three-phase circuit within 183\u2026484 V AC[reference:3].<\/li>\n<li><strong>2 C\/O Output Contacts, 5 A:<\/strong> Two changeover contacts rated 5 A nominal current and 1250 VA maximum switching capacity provide flexible control and signalling options[reference:4].<\/li>\n<li><strong>Fast Fault Response (100 ms):<\/strong> Detects and reacts to phase faults within 100 ms maximum, with a 500 ms pick-up delay to avoid nuisance tripping during supply stabilization[reference:5].<\/li>\n<li><strong>17.5 mm Modular Width:<\/strong> The same width as a single-pole circuit breaker, enabling compact panel layouts and straightforward DIN rail integration alongside protective devices[reference:6].<\/li>\n<li><strong>Transparent Setting Cover:<\/strong> A transparent cover protects the front settings from tampering and accidental adjustment, reducing maintenance interventions[reference:7].<\/li>\n<li><strong>High Mechanical Durability:<\/strong> Rated for 30,000,000 mechanical operating cycles and 10,000 electrical cycles, with a yellow LED indicating relay output status[reference:8][reference:9].<\/li>\n<\/ul>\n<h2>Technical Specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Manufacturer<\/td>\n<td>Schneider Electric<\/td>\n<\/tr>\n<tr>\n<td>Model<\/td>\n<td>RM17TG20<\/td>\n<\/tr>\n<tr>\n<td>Series<\/td>\n<td>Harmony Control Relays<\/td>\n<\/tr>\n<tr>\n<td>Product Type<\/td>\n<td>3-Phase Supply Control Relay<\/td>\n<\/tr>\n<tr>\n<td>Relay Monitored Parameters<\/td>\n<td>Phase sequence;
