Description

Overview

The Siemens 3RH2131-1BB40 is a high-performance contactor relay designed for reliable switching and control in industrial automation systems. Featuring 3 normally open (NO) and 1 normally closed (NC) contacts, this relay operates with a 24V DC control voltage and comes with screw terminals for secure and easy installation. Its compact S00 frame size makes it ideal for space-saving control panel designs.

Benefit

  • Reliable Siemens Quality – Built for long service life and stable performance

  • Compact Design – S00 frame size saves valuable panel space

  • Flexible Control – 3 NO + 1 NC contact configuration supports multiple control circuits

  • Easy Installation – Screw terminals ensure strong and secure wiring

  • Energy Efficient – Optimized 24V DC coil for reduced power consumption

Function and Application

The 3RH2131-1BB40 functions primarily as an auxiliary switching device. Its main uses include:

  • Signal Multiplication: Multiplying auxiliary contacts for use in various control loops.

  • Interlocking: Creating safety and operational interlocks in motor control circuits to prevent conflicting operations.

  • Control Panel Logic: Implementing simple relay logic for machine sequence control.

  • Control of Small Loads: Switching indicator lamps, solenoids, or very small motors.
