Specification & Description
The Siemens 3RN1011-1CB00 is a high-quality thermistor motor protection device designed to safeguard motors from potential thermal overload. This unit is engineered to provide reliable protection by monitoring the temperature of the motor's windings through connected thermistors and initiating a shutdown procedure if an overtemperature condition is detected.
Featuring a 1NO/1NC contact configuration, this device ensures a flexible integration into safety circuits, allowing for both normally open and normally closed operations. The 24 V ac/dc control supply voltage makes it suitable for a wide range of applications, and the screw terminal connection offers a secure and durable means of installation.
With a compact design, measuring 91 x 22.5 x 102 mm, the 3RN1011-1CB00 can be easily accommodated within control panels without requiring excessive space. The LED display provides clear indication of operational status, and the IP20 protection class signifies that the unit is protected against solid objects larger than 12mm, making it suitable for industrial environments.
This thermistor motor protection unit is a crucial component for any system where motor overheating could lead to downtime, equipment damage, or safety hazards. It is an essential part of a comprehensive motor management system for applications in manufacturing, processing, and other demanding industrial settings.
