Siemens Industrial Controls 3RH1921-1DA11 Switch
Optimize your control circuitry with the Siemens Sirius 3RH1921-1DA11, a precision-engineered auxiliary switch block designed for secondary switching and status feedback. This first lateral mount unit features a compact 10mm width and provides 1 NO (Normally Open) and 1 NC (Normally Closed) contact configuration. Engineered for industrial reliability, it integrates seamlessly with Sirius 3RT1 contactors and 3RH1 contactor relays from sizes S0 through S12. The side-mounted design ensures efficient panel space utilization without requiring additional front depth. Utilizing rugged screw terminals, it maintains secure electrical connections even in high-vibration HVACR environments. With a 10A current rating and a 6kV surge voltage resistance, this IEC-rated auxiliary switch is built for consistent performance in demanding motor control and automation setups. Its IP20 protection class safeguarding against unintended contact makes it a standard choice for technicians focusing on safety and European compliance (EN 50012).
Key Benefits:- Versatile Compatibility: Designed specifically for Siemens Sirius 3RT10, 3RT12, and 3RT14 series contactors across multiple frame sizes.
- Space-Efficient Side Mounting: The lateral installation allows for expanded control logic without increasing the assembly's front profile depth.
- Reliable Contact Logic: Features a mirrored 1NO/1NC contact set for interlocking, signaling, or secondary control circuits.
- High Mechanical Life: Rated for up to 10 million operating cycles, ensuring longevity in high-frequency switching applications.
- Can I mount multiple 3RH1921-1DA11 blocks on one contactor? Yes, these side-mounted blocks can be added to the left or right sides, provided the specific contactor configuration and EN 50012 guidelines for total contact count are followed.
- Is this switch compatible with 3RT2 series contactors? No, this variant is specifically intended for the older 3RT1 series; for 3RT2 models, the 3RH29 series is typically required.
- Does this require special tools for installation? No, it features a snap-on mechanism for easy attachment to the side of the 3RT1 frame, though a standard screwdriver is needed for the terminal connections.
