The Siemens 3RV1901-1C is a lateral auxiliary switch from the SIRIUS product line, specifically designed for integration with Siemens circuit breakers of sizes S00, S0, S2, and S3. This component provides 2 normally closed (NC) instantaneous contacts, facilitating auxiliary control and signaling functions within electrical systems.
With a compact design, it measures 9.5 mm in width, 90 mm in height, and 70 mm in depth, utilizing a plug-in fixing method for easy installation. The switch operates within a temperature range of -20°C to +60°C during operation and -50°C to +80°C during storage. Its auxiliary circuit connections are made via screw-type terminals, supporting conductor cross-sections from 0.5 to 2.5 mm².
Operational current ratings include up to 10A at AC-12 across various voltages (24V, 230V, 400V, 690V) and specific ratings for AC-15 and DC-13 circuits. For instance, at AC-15, it can handle up to 6A at 24V and 4A at 230V. At DC-13, it supports up to 2A at 24V.
This product is noted as phased-out, with the SIRIUS 3RV2 series, specifically the 3RV2901-1C, being its preferred successor. It holds certifications including CE, UL, CSA, and CCC.
