Product Details

The Siemens 3RH2911-1HA11 is a front-mounted auxiliary contact block designed for use with Siemens SIRIUS contactor relays and motor starters. This compact contact module expands the control capabilities of your switching devices by adding one normally open (NO) and one normally closed (NC) auxiliary contact.

Key Features:

  • Contact configuration: 1 normally open (NO) + 1 normally closed (NC)
  • Current rating: 20A per contact for reliable switching performance
  • Front mounting design for easy installation and maintenance access
  • Compatible with SIRIUS 3RT2 and 3RH2 series contactors and relays
  • Snap-on attachment mechanism for quick, tool-free installation
  • Compliant with international standards including IEC and UL approvals
  • Screw terminal connections for secure wiring

This auxiliary contact block is ideal for signaling, interlocking, and control circuit applications in industrial automation systems. The front-mounted design allows for easy retrofitting to existing contactors without removing the device from the panel, minimizing downtime during installation or modification.

Great price and quick delivery. The only issue I had was that I did not receive a shipping confirmation and tracking info. I had to contact customer service and they weren't even clear on shipping info. While I was waiting for a reply, the tire showed up at my house. I received shipping confirmation the day after it arrived.
