REFERENCE MATERIAL
Check the document’s model and revision before use.
3RH2911-1HA11 is a front-mounted Siemens SIRIUS auxiliary contact block with 1 NO + 1 NC. It uses screw terminal connections. Select the contact logic, mounting arrangement and permitted base device together; contact count alone is insufficient.
The highlighted models address the main selection differences. Each link opens a separate product. Matching one specification does not establish interchangeability; use the complete order number and installation requirements.

For contactors 3RT2 and contactor relays 3RH2. Check the exact base device, other fitted accessories and available mounting space before assembly. The family statement does not mean every possible contact-block combination is permitted.
The manufacturer lists .1/.2, .3/.4, –/–, –/–. Contact sequence: 1 NC, 1 NO, –, –. Match these markings to the control drawing; do not transfer wire positions from a block with the same NO/NC count but different numbering.
This block adds auxiliary switching paths to a suitable base device. It is not a standalone coil-operated relay, a motor power pole or a protective device. Select each switched load using the auxiliary-contact electrical ratings and the required control-circuit duty.
This order number identifies the auxiliary contact block. The base contactor or contactor relay is a separate product; no combined package is established here.
No. This model also requires front mounting, the stated base-device scope, suitable connections and the correct contact numbering.
