Information About 3RH1131-1BF40
The 3RH1131-1BF40 is part of Siemens’ SIRIUS 3RH1 auxiliary contactor series, engineered for long mechanical endurance and precise switching performance. It features screw-type terminals, IP20 front protection, and compatibility with S00 contactor accessories. Its 110 V DC coil offers stable operation within the allowable voltage range and meets IEC 81346-2 classification standards. As a phased-out model, it is commonly used as a service replacement for legacy control panels, with the preferred modern successor being the Siemens 3RH2131-1BF40.
Key Features:
- Auxiliary Contactor Relay: Designed for signaling, interlocking, and auxiliary switching functions in automation systems.
- 3NO + 1NC Contacts: Provides versatile contact combinations for control logic applications.
- 110 V DC Coil: Stable DC operation with defined opening and holding power for precise response.
- Compact S00 Size: Fits into small control cabinets and supports Siemens S00 mounting accessories.
- High Mechanical Durability: Typical service life up to 30 million switching cycles depending on configuration.
- IP20 Front Protection: Ensures safe operator access and basic protection inside control panels.
- Shock Resistant: Rated 10 g/5 ms and 5 g/10 ms for industrial vibration and shock conditions.
- Wide Ambient Temperature Range: Operates from –25 °C to +60 °C with extended storage limits.
- DIN-Rail & Screw Mounting: Offers flexible installation using snap-on capability and screw fasteners.
- Screw-Type Terminals: Accepts a wide range of solid and stranded conductors for secure wiring.
The 3RH1131-1BF40 delivers the reliability and precision required for auxiliary switching in industrial control and automation environments.
