Siemens Industrial Controls 3RH2911-1HA11 Contact
The Siemens 3RH2911-1HA11 is a high-performance SIRIUS auxiliary contact block designed for front mounting on 3RT2 contactors and 3RH2 contactor relays. This 2-pole unit features a 1NO + 1NC (Normally Open and Normally Closed) configuration, providing essential signaling and interlocking capabilities for industrial motor control circuits. Engineered for seamless integration, it utilizes a snap-on mounting system that allows for tool-free installation across various frame sizes, including S00, S0, and S2. With a rated insulation voltage of 690V and a surge voltage resistance of 6kV, this module ensures robust electrical separation and high signal reliability.
Built for demanding environments, the 3RH2911-1HA11 auxiliary switch offers a mechanical service life of up to 10 million operating cycles. The screw terminal connections provide secure, vibration-resistant wiring, while the IP20 protection class ensures safety in standard panel configurations. This Siemens auxiliary contact is an industry standard for professionals requiring precise feedback loops in automation and HVACR control systems. Its compact design facilitates high-density mounting without compromising the thermal performance of the primary power contactor.
Key Benefits:- Universal Compatibility: Designed for use with the entire Siemens SIRIUS 3RT2 series and 3RH2 contactor relays.
- Simplified Installation: The front-mounted snap-on mechanism allows for rapid field upgrades and maintenance with no specialized tools.
- Enhanced Logic Control: Provides integrated 1NO and 1NC contacts to handle auxiliary signaling, status indication, or electrical interlocking.
- Industrial Durability: Rated for high-frequency switching with an electrical endurance of approximately 200,000 cycles at AC-15.
- Reliable Connections: Standard screw terminals ensure stable contact even in high-vibration applications.
Which contactors are compatible with the 3RH2911-1HA11?
This block is specifically designed for the Siemens SIRIUS 3RT2 power contactors and 3RH2 contactor relays, covering frame sizes S00 through S3.
Can I install this on the side of the contactor?
No, the 3RH2911-1HA11 is a top-mounted / front-mounted auxiliary switch. For lateral mounting, you must select the 3RH2911-1DAxx or similar side-mount series.
Does this unit support positively driven or mirror contacts?
Yes, when used with 3RH contactor relays, the contacts are positively driven. When paired with 3RT power contactors, they function as mirror contacts per IEC 60947-4-1.
