This Siemens 3RV20211AA15 circuit breaker, part of the SIRIUS 3RV2 series, is specifically designed for motor protection applications. It features a thermal magnetic overload release with an adjustable current response value ranging from 1.1 to 1.6 A and a nominal operational current of 1.6 A.
The breaker is built with 3 poles and supports a rated operating voltage of up to 690 V for AC-3 and AC-3e applications. It includes standard switching capacity with transverse auxiliary switches, providing 1 normally open (NO) and 1 normally closed (NC) contact. The unit is rated for a breaking capacity of 100 kA at 240 V AC.
Designed for easy installation, this circuit breaker mounts on a standard DIN rail. It operates within an ambient temperature range of -20 to +60 °C and has a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts. The ATEX directive protection type is Ex II (2) GD, with certificate DMT 02 ATEX F 001.
Key electrical characteristics include a power loss of 7.25 W at AC in hot operating state and a surge voltage resistance of 6 kV. It also features phase failure detection for enhanced safety.
