The Siemens SIRIUS 3RV20211EA25 is a size S0 circuit breaker specifically designed for motor protection applications. It features a thermal magnetic overload release with an adjustable current response range of 2.8 to 4 A and a trip class of CLASS 10. This 3-pole breaker operates at a rated voltage of up to 690 V and has an operational current rating of 4 A at 400 V (AC-3 and AC-3e).
Equipped with a rotary actuator and DIN rail mounting, the 3RV20211EA25 includes transverse auxiliary switches with 1 normally closed (NC) and 1 normally open (NO) contact. It offers a maximum short-circuit breaking capacity of 100 kA at 240 V AC. The breaker operates within an ambient temperature range of -20 to +60 °C and meets various international approval standards including ATEX, CCC, CE, CSA, EAC, IECEx, UL, and VDE.
Key protective functions include phase failure detection. The mechanical and electrical endurance for both main and auxiliary contacts is rated at a typical 100,000 switching cycles. This circuit breaker is suitable for industrial environments requiring reliable motor protection.
