Description
The Siemens 3RN1011-1CK00 is a thermistor motor protection unit designed for monitoring and safeguarding motors against overheating caused by excessive thermal loads. This model features a standard evaluation unit with manual operation, offering both one normally open (NO) contact and one normally closed (NC) contact configuration. Compatible with input voltage options of 230 V AC or 110 V AC, it uses screw terminal connections to ensure secure installation within industrial control systems.
The device conforms to stringent operational requirements and facilitates the protection of motor windings by interfacing with thermistor sensors embedded in the equipment. Its compact packaging dimensions (99 mm x 29 mm x 107 mm) allow for efficient integration into control panels, while its net weight of only 0.19 kg reduces material handling efforts during assembly processes.
Although this specific model is being phased out, buyers seeking equivalent functionality are directed toward the successor product: Siemens model number **3RN2011-1BW30**. The replacement offers updated specifications while maintaining continuity in application suitability.
Engineers can utilize this legacy unit for applications requiring robust thermal monitoring where lifecycle considerations align closely with production schedules involving non-returnable components manufactured to order. Detailed technical data sheets are available upon request for comprehensive specifications pertinent to system design assessments and procurement decisions.
