Description

The 3RN1010-1CW00 thermistor motor protection relay is a phased-out Siemens product, engineered for monitoring thermistors in motor windings to provide overtemperature protection. This standard evaluation unit operates with AUTO functionality and includes one normally open (NO) and one normally closed (NC) contact. Its versatile design supports input voltages ranging from 24 V to 240 V AC/DC and connects via screw terminals, ensuring reliable integration into control systems.

This device was classified as "C" under Siemens’ product lifecycle designation, indicating it is custom-manufactured but not reusable or returnable for credit. With compact packaging dimensions of 99 x 29 x 107 mm and a net weight of only 0.140 kg, the relay offers space-saving installation in various industrial environments.

While this model has been discontinued, the preferred successor — the 3RN2010-1CW30 — offers updated features without ATEX approval. Detailed specifications for legacy installations remain accessible in downloadable technical data sheets. Distributors and engineers can rely on its precise operation within standard temperature protection circuits prior to transitioning to newer models that meet evolving standards.
