The Siemens 3RN1012-1CB00 is a sophisticated motor protection relay designed to safeguard motors from potential damage due to overheating. This device utilises thermistor sensors to monitor the temperature of the motor windings, providing real-time protection and ensuring the longevity and reliability of your motor-driven applications.
Crafted for versatility, the relay features a dual voltage rating of 24 V ac/dc, making it suitable for a wide range of control supply voltages. The inclusion of both a normally open (NO) and a normally closed (NC) contact allows for flexible integration into various control circuits, accommodating different safety and control strategies.
Installation is made simple with options for both screw and snap-on mounting, ensuring a secure fit in a variety of settings. The compact dimensions of 23 x 91 x 102 mm allow for efficient use of space inside control cabinets. The screw terminal connections provide a robust and reliable means of wiring, further simplifying the installation process.
The relay is equipped with an LED display for clear indication of operational status, and it includes a reclosing lockout feature to prevent automatic restarting of the motor under fault conditions, enhancing the protection offered to your equipment.
With an ambient operating temperature range of -25 to +60°C, the Siemens 3RN1012-1CB00 is resilient and capable of performing in diverse environmental conditions. This makes it an ideal choice for a broad spectrum of industrial applications where motor protection is paramount.
