Siemens Industrial Controls 3RH2921-1DA11 Switch
The Siemens 3RH2921-1DA11 is a high-performance lateral auxiliary switch block specifically engineered for the expansion of control circuit contacts. Designed for veterans in the field, this Sirius auxiliary contact features a robust 1NO + 1NC (1 Normally Open and 1 Normally Closed) configuration, providing essential feedback for motor control logic. Its side-mount architecture allows for a space-efficient 10mm profile, attaching seamlessly via snap-on mounting to the left or right side of 3RT2 series contactors and 3RH2 contactor relays without the need for additional tools.
Built with screw terminals to ensure secure connections in high-vibration industrial environments, the 3RH2921-1DA11 supports a rated insulation voltage of 690V and an operational current of up to 6A at AC-15 (230V). This unit is fully compatible with S00, S0, S2, and S3 frame sizes, functioning as a mirror contact to indicate the status of the main power contacts reliably. Its IP20 protection rating and wide operating temperature range (-25 to +60°C) make it a standard choice for demanding HVACR and automation panels.
Key Benefits:- Tool-Free Installation: Integrated snap-on mechanism for rapid lateral attachment to 3RT2 contactors.
- High Reliability: Features positively driven contacts when used with 3RH relays, ensuring accurate signaling for safety circuits.
- Space-Saving Design: The 10mm lateral width minimizes rail footprint while adding dual-pole functionality.
- Durable Construction: Maintains mechanical endurance up to 10 million switching cycles for long-term operational stability.
- Which contactor series is this switch compatible with? It is designed for the Siemens Sirius 3RT2 power contactors and 3RH2 contactor relays.
- Can I mount this on either side of the contactor? Yes, the 3RH2921-1DA11 supports lateral mounting on both the left and right sides.
- What is the maximum current rating for the contacts? The operational current (AC-15) is rated at 6A at 230V, with a thermal current (Ith) of 10A.
