Description

**Siemens 3RN1000-1AB00 Thermistor Motor Protection Evaluation Unit**

The Siemens 3RN1000-1AB00 is a compact thermistor motor protection evaluation unit engineered for thermal monitoring and safeguarding of electric motors. Designed to process input from PTC thermistors embedded in motor windings, this device delivers precise overload protection by evaluating temperature changes critical to equipment operation and longevity. It operates efficiently with an automatic reset function and supports a power supply of 24 V AC/DC, enabling seamless integration within industrial control systems.

Featuring screw terminal connections for secure wiring, the evaluation unit measures 89.50 x 28.50 x 102.00 mm, making it suitable for installations where space is constrained. With a net weight of only 0.116 kg, it ensures easy handling during setup or replacement procedures. Classified under product type "C," this module caters to specific applications requiring highly tailored production items that cannot be reused or returned once issued.

Though now discontinued, the preferred successor model is designated as the Siemens 3RN2000-1AA30 (without ATEX approval), which builds upon its predecessor’s functionality while offering updated features suited for contemporary industrial demands. Detailed technical data sheets are available to assist engineers in selecting and integrating motor protection solutions into their workflows effectively.
