Siemens Thermistor Motor Protection Monitoring Relay DIN Rail Mount 0V AC 0 V AC 3RN2023-2DW30

Siemens 3RN2023-2DW30 thermistor motor protection monitoring relay is designed for precise motor temperature monitoring and overload protection in various industrial applications. This DIN rail mountable relay offers advanced sensing using two separate PTC sensor circuits to evaluate the winding temperature of motors for overloading or overheating conditions. It effectively cuts off power to the motor when temperature exceeds preset thresholds, thereby preventing damage and downtime.

The relay features a compact design with spring terminal connections for quick and secure installation. It includes a test/reset button, wire breakage monitoring, and short circuit detection capabilities to ensure operational safety and reliability. An LED status indicator provides visual feedback for easy diagnostics.

Operating at 0 V AC input voltage with a power consumption of 1.8W and contact current rating of 5A, the monitoring relay accommodates challenging environments, including hazardous industrial areas, backed by ATEX certification. Its operational temperature range from -25°C to +60°C and an IP20 protection rating make it versatile for demanding settings.

Physical dimensions are 100 mm in height, 22.5 mm width, and 91.6 mm length, supporting compact panel assembly. This relay series is engineered for a long mechanical life of 10 million cycles, providing high endurance against shocks and vibrations commonly found in industrial use.
