The Siemens 3RV2901-2E is a meticulously engineered auxiliary switch designed to offer reliable and efficient performance for industrial control applications. This transverse auxiliary switch is compatible with Siemens circuit breakers sizes S00, S0, S2, and S3, ensuring a broad range of usability across various systems. It features a spring-loaded terminal connection that simplifies installation and maintenance, providing a secure and durable electrical connection.
With a compact design, the switch measures 45mm in width, 13mm in height, and 17mm in depth, making it an ideal choice for space-constrained environments. The 3RV2901-2E operates with an IP20 protection class on the front, signifying a basic level of protection against solid objects. It is designed to withstand ambient operating temperatures ranging from -20°C to +60°C and storage temperatures from -50°C to +80°C, ensuring consistent performance in diverse working conditions.
The auxiliary switch features one normally closed (NC) and one normally open (NO) contact for instantaneous switching, providing flexibility in circuit control. It is capable of handling operating currents of up to 2.5A at 24V and 230V in AC-12 applications, with a maximum current rating of 10A. For DC-13 applications, it can manage 1A at 24V, 0.3A at 48V, and 0.15A at 60V.
This product is certified with CE, UL, CSA, and CCC approvals, reflecting its compliance with international standards and its suitability for global use. The Siemens 3RV2901-2E auxiliary switch is a robust and versatile component, essential for enhancing the operational efficiency and reliability of industrial control systems.
