Siemens Industrial Controls 3RH2911-1HA31 Contact Block
Integration of the Siemens 3RH2911-1HA31 into your control logic setup provides a high-reliability solution for expanding the contact capacity of SIRIUS 3RT2 contactors and 3RH2 contactor relays. This front-mount auxiliary contact block features a 3NO + 1NC (3 Normally Open / 1 Normally Closed) configuration, allowing for complex interlocking, signaling, and feedback loops within industrial motor control circuits. Designed for snap-on mounting, it eliminates the need for specialized tools and reduces downtime during panel assembly or field retrofits.
Engineered for high-demand HVACR and industrial automation environments, the 3RH29111HA31 supports an operational current of up to 10A at 230V (AC-12) and maintains signal integrity even at lower voltages (17V, 1mA). The unit utilizes screw-type terminals for secure conductor termination, supporting wire cross-sections up to 2.5 mm². With a mechanical service life of 10 million cycles and IP20 protection, this 4-pole module ensures long-term switching stability for PLC inputs and status indication in motor starter assemblies. It is the direct replacement for the legacy 3RH1911-1HA31 series, ensuring compatibility with modern Siemens SIRIUS Size S00 to S3 frames.
Key Benefits:- Precise Signal Logic: Provides 3NO + 1NC contacts to handle simultaneous status feedback and safety interlocking.
- Universal SIRIUS Compatibility: Engineered for seamless interface with Siemens 3RT2 contactors and 3RH2 contactor relays.
- Rapid Field Installation: Front-facing snap-on mounting mechanism enables quick expansion without disassembling existing wiring.
- Industrial-Grade Durability: Rated for up to 690V insulation voltage with a high electrical endurance of 200,000 cycles at AC-15.
- Compact Control Design: Maintains a slim profile to maximize DIN rail space within crowded electrical enclosures.
What is the contact arrangement of the 3RH2911-1HA31?
This block features 4 poles in a 3NO + 1NC configuration, meaning three contacts are normally open and one is normally closed in the de-energized state.
Which Siemens contactors is this auxiliary block compatible with?
It is designed for the SIRIUS 3RT2 series (Sizes S00, S0, S2, and S3) and 3RH2 contactor relays.
Can this block be used for low-level PLC signaling?
Yes, the 3RH2911-1HA31 is designed for high contact reliability, making it suitable for switching low-current electronic signals and PLC digital inputs.
