The Siemens 3RV20211HA25 is a robust circuit breaker from the SIRIUS 3RV2 series, specifically engineered for motor protection applications. This S0 size breaker offers a thermal magnetic trip mechanism with an adjustable overload release current range of 5.5 to 8 Amperes, and a fixed N-release of 104A. It is designed for a rated operating voltage of up to 690V and has a rated operational current of 8A at 400V.
Featuring 3 poles for the main circuit, this device includes transverse auxiliary switches with 1 normally open (NO) and 1 normally closed (NC) contact. The breaker boasts a high breaking capacity of 100 kA at 240V AC and meets CLASS 10 trip class standards. It is suitable for DIN rail mounting and operates reliably within an ambient temperature range of -20 to +60 °C.
Compliance includes ATEX certification (Ex II (2) GD), along with CCC, CE, CSA, EAC, IECEx, UL, and VDE approvals, making it suitable for a wide range of industrial environments. The mechanical and electrical endurance is rated for a typical 100,000 switching cycles.
