3RH2911-2FA22 NEW ORIGINAL

The Siemens 3RH2911-2FA22 is a front-mounting auxiliary switch block from the SIRIUS 3RH2 series, designed to expand the control circuit capacity of SIRIUS 3RT2 power contactors and 3RH2 contactor relays. It provides a 2 NO + 2 NC contact configuration with spring-loaded (cage clamp) terminals, enabling reliable signaling, interlocking, and status feedback in industrial control panels. This auxiliary switch is a current, active product (PLM status PM300: Active Product), ensuring long-term availability for new installations and maintenance alike . The spring-loaded terminals provide maintenance-free, vibration-resistant connections, while the front-mounting design allows the block to be installed without tools and independently of the contactor size.
