3RV20111BA25

The Siemens 3RV20111BA25 is a robust circuit breaker from the SIRIUS 3RV2 series, specifically designed for motor protection applications. This S00 size breaker offers a 3-pole configuration with a thermal magnetic overload release, allowing for adjustable current response values ranging from 1.4 to 2 Amperes.

It operates with a trip class of 10, ensuring reliable protection for motors. The breaker supports a wide operating voltage range from 20 to 690V and can handle operational currents up to 2A at 400V (AC-3 and AC-3e). It also includes transverse auxiliary switches with 1 normally open (NO) and 1 normally closed (NC) contact, suitable for AC-15 and DC-13 control circuits.

Designed for standard switching capacity, the 3RV20111BA25 features spring-type terminals for secure connections and is mountable on a DIN rail. Its mechanical and electrical endurance is rated for a typical 100,000 switching cycles. The breaker also incorporates phase failure detection for enhanced safety.

Environmental conditions for operation include an ambient temperature range of -20 to +60°C and a relative humidity of 10-95%. It is certified according to ATEX directive 2014/34/EU (Ex II (2) GD) and carries multiple approval agency certifications including CE, CSA, UL, and VDE.
