This Siemens 3RV20210HA25 is a motor protection circuit breaker from the SIRIUS 3RV2 series. It is designed for robust protection with an adjustable overload release range of 0.55 to 0.8 Amps and a fixed short-circuit release of 10 Amps. The breaker has a size S0 frame and a 3-pole configuration, suitable for operating voltages up to 690V.
Key features include a trip class of CLASS 10 and thermal overload release. It also incorporates phase failure detection for enhanced safety. The unit is equipped with transverse auxiliary switches, providing 1 normally open (NO) and 1 normally closed (NC) contact. The mechanical and electrical endurance for both main and auxiliary contacts is rated at a typical 100,000 switching cycles.
Environmental and compliance data includes ATEX directive type of protection (Ex II (2) GD) and a suitability certificate (DMT 02 ATEX F 001). It operates within an ambient temperature range of -20 to +60°C and can be mounted on a DIN rail. The breaker is compliant with RoHS3, REACH Unaffected, and has an MSL of 1.
