The Siemens SIRIUS 3RV20211FA25 is a circuit breaker specifically designed for motor protection applications. It operates with a thermal magnetic trip mechanism and offers an adjustable current response value between 3.5 and 5 Amperes.
This 3-pole breaker is rated for a maximum operating voltage of 690V and has a breaking capacity of 100 kA at 240V AC. It includes transverse auxiliary switches with 1 normally open (NO) and 1 normally closed (NC) contact, suitable for AC-15 and DC-13 applications.
The device is built for reliability, featuring a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts. It operates within an ambient temperature range of -20 to +60 °C and is designed for DIN rail mounting, making installation straightforward in control panels.
Compliance with ATEX directive 2014/34/EU is indicated by its Ex II (2) GD protection type and certificate DMT 02 ATEX F 001. The breaker also meets general technical standards with a trip class of CLASS 10.
