Siemens Industrial Controls 3RH2911-1MA11 Aux
Integrate the Siemens 3RH2911-1MA11 auxiliary switch block into your control panel for dependable status feedback and interlocking functions. As a veteran-grade front-mounted auxiliary contact, this unit is engineered for the SIRIUS 3RT2 contactors and 3RH2 contactor relays, covering frame sizes S00 through S3. It features a 1NO/1NC contact configuration with a bottom-entry wiring design, which is essential for maintaining clean wire management in tight enclosures where top-side access is restricted. The screw terminal connections ensure high contact reliability, rated for 10 million mechanical cycles and tested for a failure rate as low as one switching operation per 100 million at 17V/1mA.
This auxiliary switch block utilizes a tool-free snap-on mechanism for immediate deployment onto the front face of your primary switching device. The IP20 protection class ensures safety during maintenance, while the 690V insulation rating qualifies it for heavy-duty industrial environments. By utilizing the 3RH2911-1MA11, technicians can easily expand control logic circuits without increasing the footprint of the contactor, making it a standard choice for motor starters and complex automation sequences where 1NO/1NC front auxiliary functionality is required.
Key Benefits- Optimized Wire Routing: Bottom-side cable entry simplifies lead dressing in crowded control cabinets.
- Universal Compatibility: Seamlessly snaps onto SIRIUS 3RT2 and 3RH2 series across multiple frame sizes.
- High Contact Integrity: Designed for gold-standard reliability in both signaling and interlocking applications.
- Simplified Installation: Front-mount, snap-on design requires no additional mounting hardware or tools.
Is the 3RH2911-1MA11 compatible with older 3RT1 series contactors?
No, this specific auxiliary block is part of the SIRIUS Innovation line designed for 3RT2 and 3RH2 series equipment. Always verify your contactor generation before installation.
What is the purpose of the bottom-entry version?
Standard auxiliary blocks often use top or side entry; the bottom-entry design on the 3RH2911-1MA11 is specifically utilized when wiring from below is necessary to avoid interference with other DIN-rail components or to maintain specific airflow paths.
Can this block be used for safety-related mirror contact functions?
Yes, when used with 3RT2 power contactors, these contacts function as mirror contacts according to IEC 60947-4-1, and as positively driven contacts in 3RH2 contactor relays per IEC 60947-5-1.
