6SE6400-0PT100-0AA0 Siemens | Motor Temperature Protection

Siemens 6SE6400-0PT100-0AA0 MICROMASTER 4 PT100 Temperature Sensor Module

The 6SE6400-0PT100-0AA0 (Model: 6SE6400-0PT100-0AA0) is a precision motor protection accessory specifically designed for the Siemens MICROMASTER 4 inverter series, including the MM420, MM430, and MM440. This plug-in module enables the inverter to interface directly with PT100 Resistance Temperature Detectors (RTDs). By providing real-time thermal feedback, the 6SE6400-0PT100-0AA0 (Part Number: 6SE6400-0PT100-0AA0) allows the drive to implement sophisticated thermal management strategies, such as automated derating or emergency shutdown, ensuring the longevity of motor windings in high-load industrial environments.

Unlike standard I/O modules, the 6SE6400-0PT100-0AA0 (Model: 6SE6400-0PT100-0AA0) is calibrated for high-accuracy resistance-to-temperature conversion. It eliminates the need for external temperature transmitters, reducing both wiring complexity and hardware costs. The module is essential for applications where motors operate in variable ambient temperatures or under heavy duty cycles where standard I²t thermal modeling is insufficient to protect the hardware.

Detailed Technical Specifications

The 6SE6400-0PT100-0AA0 (Model: 6SE6400-0PT100-0AA0) provides deterministic temperature data directly to the inverter's control logic.
