Description

The Siemens 3RH1921-1FA22 is an attachable mounting block that conforms to DIN EN 50005 standards, offering a reliable interface solution for industrial applications. Engineered as part of the SIRIUS modular system, this unit features a 4-pole configuration with two normally open (NO) and two normally closed (NC) contacts. It provides secure and adaptable connectivity to control circuits, meeting stringent requirements for electrical operation in industrial automation environments.

Its compact form factor has packaging dimensions of 51 mm x 45 mm x 64 mm and a net weight of only 0.065 kg, making it suitable for installations with spatial constraints. The product is classified under category C, indicating it was custom-manufactured and not intended for reuse or return against credit. While phased out in favor of the SIRIUS 3RH2 series successor, its design ensures compatibility with legacy systems adhering to EN standards.

This mounting block is particularly suited for systems requiring dependable switching functions within control cabinets or distributed setups across varied industries such as manufacturing plants or process automation facilities. Detailed documentation is available via downloadable product data sheets to ensure seamless integration into existing configurations while complying with safety regulations and operational reliability norms.
