The Siemens 3RV20211DA25 is a circuit breaker used for electrical protection in various applications. It features a size of S0 and an adjustable current response range of 2.2 to 3.2A. The device has a power loss of 7.25 W at AC in hot operating state and an insulation voltage of 690 V with pollution degree 3. It provides surge voltage resistance rated at 6 kV and shock resistance according to IEC 60068-2-27 of 25g for 11 ms. The circuit breaker is rated for 100,000 mechanical and electrical switching cycles, ensuring durability. It complies with ATEX Directive Ex II (2) GD and has a certificate of suitability DMT 02 ATEX F 001. Designed for installation at altitudes up to 2000 meters, it operates within ambient temperatures of -20°C to +60°C and storage/transport temperatures of -50°C to +80°C. The device is suitable for environments with relative humidity of 10% to 95% during operation. It features three poles and includes auxiliary contacts with transverse design, one normally open (NO) and one normally closed (NC). It also detects phase failure but does not detect ground faults.
