3RH1131-2JB40 SIEMENS

The 3RH1131-2JB40 is a contactor relay manufactured by Siemens, designed for switching electrical circuits in industrial control applications. It features a configuration of 3 normally open (NO) contacts and 1 normally closed (NC) contact, providing versatile control options. The relay operates on a 24 V DC control voltage, with an operating range of 0.7 to 1.25 times the rated voltage, ensuring reliable performance even with voltage fluctuations. An integrated diode provides protection against voltage spikes, enhancing the relay's durability and lifespan. The relay utilizes spring-type terminals for secure and easy wiring, reducing installation time and improving connection reliability. It is a Size S00 contactor relay, indicating its compact dimensions and suitability for space-constrained applications. Please note that the 3RH1131-2JB40 is a phased-out product. The preferred successor is the SIRIUS 3RH2 series, specifically model 3RH2131-2JB40, which offers improved features and performance. Consider the successor model 3RH2131-2JB40 for new installations or replacements.
