Siemens Contactor Relay 110V DC Coil 4-Pole 6A 690V AC 3NO/1NC 3RH2131-1BG40

Siemens 3RH2131-1BG40 Contactor Relay features a 110V DC coil and a 4-pole configuration tailored for industrial automation and control applications. Rated for 6A contact current and suitable for contact voltages up to 690V AC, this relay delivers robust performance in electrical circuits requiring reliable switching and control.

Compactly sized at 45mm width, 45mm length, and 73mm depth, it is designed for easy installation in tight control gear panels. The relay includes 3 normally open (NO) and 1 normally closed (NC) contact configuration, allowing versatile control circuit designs. Screw-type terminals ensure secure and vibration-resistant electrical connections.

Operating reliably across a temperature range from -25°C to 60°C, this Siemens relay withstands demanding industrial environments. It complies with a comprehensive set of international standards such as CCC, UL, CE, CSA, EAC, IEC 60529, IEC 60947-5-1, and IEC 61508, ensuring safety and quality.

The high degree of contact stability at low voltages and currents makes it compatible with solid-state circuits with minimum currents as low as 1mA at voltages above 17V. This enhances its applicability in modern automated control systems. The product supports expansion through snap-on auxiliary switch blocks, allowing up to four additional contacts to be added for increased control circuit complexity.

This contactor relay is ideal for use in industrial automation, manufacturing plants, HVAC systems, and commercial electrical control panels. Developed and manufactured in Germany, it guarantees durability, precision, and adherence to stringent manufacturing standards.
