This Siemens SIRIUS 3RV2 series circuit breaker, part number 3RV20211CA15, is specifically designed for motor protection applications. It features a size S0 frame and a thermal magnetic overload release with an adjustable current response value between 1.8 and 2.5 A. The breaker has 3 poles and is rated for a maximum operating voltage of 690 V.
It includes standard switching capacity with transverse auxiliary switches, providing 1 normally open (NO) and 1 normally closed (NC) contact. The breaker is suitable for DIN rail mounting and operates within an ambient temperature range of -20 to +60 °C. Key electrical specifications include a maximum short-circuit breaking capacity of 100 kA at 240 V.
Additional technical data includes a power loss of 7.25 W at rated current and a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts. The device meets ATEX directive requirements for hazardous environments.
This circuit breaker is ideal for protecting electric motors against overloads, short circuits, and phase failures. Its robust design and compliance with various international standards ensure reliable operation in industrial settings.
