Siemens 3RN2010-1CW30

The Siemens 3RN2010-1CW30 is a thermistor motor protection relay designed to monitor motor temperature and prevent overheating. This compact evaluation unit operates within a voltage range of 24 to 240 VAC/DC and features one normally open (NO) and one normally closed (NC) contact for versatile control options. It includes automatic reset functionality and LED indicators that clearly show the device's status, whether ready or tripped. Additionally, the relay offers galvanic isolation for enhanced safety and signal integrity. Distributed by BSP Automation, this unit serves as the modern replacement for the earlier 3RN1010-1CW00 model, providing reliable and efficient motor protection in a streamlined form.
