New Original Siemens 3RN1010-2CM00 SIRIUS Thermistor Motor Protection Relay Full English Introduction<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The 3RN1010-2CM00 is an original Siemens SIRIUS series compact thermistor motor protection relay, designed for real-time winding temperature monitoring and overheat protection of three-phase industrial motors equipped with Type A PTC thermistor sensors embedded inside motor windings. It operates on closed-circuit monitoring principle and supports automatic reset mode, adopting standard DIN rail mounting structure with 22.5mm slim housing width.<\/div>\n<\/div>\n
\n
This relay provides comprehensive fault detection including PTC sensor wire break, sensor short-circuit and motor over-temperature. It is widely matched with asynchronous motors, servo motors, fan motors, pump motors and compressor motors applied in packaging machinery, textile equipment, HVAC systems, metal processing machines and logistics conveying lines. The product complies with IEC 60947, VDE 0660 standards and ATEX explosion-proof certification, suitable for both general workshop and hazardous gas\/dust working environments. New original units feature consistent electrical performance, full RoHS compliance and stable long-term continuous operation.<\/div>\n<\/div>\n
\n

2. Main Core Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Real-time temperature monitoring of motor windings via built-in PTC thermistor signal evaluation circuit<\/li>\n
  2. Automatic tripping output when PTC resistance exceeds over-temperature threshold to cut motor control circuit<\/li>\n
  3. Automatic reset function after temperature drops back to safe range without manual operation<\/li>\n
  4. Built-in wire break and short-circuit detection for PTC sensor wiring to avoid blind monitoring failure<\/li>\n
  5. Dual LED status indicators to display normal ready state and over-temperature tripped state separately<\/li>\n
  6. Integrated test button for on-site quick function verification without heating the actual motor<\/li>\n
  7. 1 changeover contact (1NO + 1NC) for signal feedback or main circuit interlock control<\/li>\n
  8. Galvanic isolation between sensor circuit and control power circuit to prevent signal interference<\/li>\n
  9. Closed-circuit self-monitoring design, triggers alarm when control supply voltage loses power<\/li>\n
  10. Slim DIN rail installation, compatible with standard electrical cabinet internal layout<\/li>\n<\/ol>\n<\/div>\n
    \n
