Siemens 3RH2 Series Contactor Relay, 24V Coil Voltage, 10A Contact Current - 3RH2131-1FB40

This contactor relay is an auxiliary switching device designed for control circuits in industrial electrical installations. It operates from a 24V DC control supply and provides multiple instantaneous auxiliary contacts for switching and interlocking tasks. The unit is intended for DIN‑rail mounting in control panels and is suitable for use across a wide ambient temperature range in applications requiring compact, repeatable switching.

Features and Benefits:

• 24V control supply for consistent Coil operation
• 10A contact current supporting moderate load switching
• 600V DC and 690V AC contact voltage for wide voltage range
• Integrated diode for suppressed Coil transients and protection
• Screw terminals enabling secure conductor connections

Applications

• Suitable for PLC‑controlled motor starter circuits
• Used for signal switching in automation control panels
• Ideal for safety‑related switching OFF
• Can be used in DC power distribution switching schemes
• Suitable for retrofit on 35 mm DIN‑rail assemblies

What are the operating temperature limits for the device?

It functions within an ambient temperature range of -25°C to +60°C.

How many and what type of auxiliary contacts are provided?

It includes three normally open and one normally closed instantaneous auxiliary contacts.

What mounting and connection methods does it use?

It mounts on a 35 mm DIN‑rail and uses screw‑type terminals for auxiliary and control circuits.

What are typical Coil power consumption figures?

Closing and holding power for the magnet Coil are both specified at 4 W.

What mechanical service life can be expected under normal use?

The contactor’s mechanical life is typically 30,000,000 operating cycles.

Note

The OFF-delay of the NO contact and the ON-delay of the NC contact are increased if the contactor coils are attenuated against voltage peaks (noise suppression diode 6 to 10 times; diode assemblies 2 to 6 times, varistor +2 to 5 ms).
