The Siemens 3RV203244SA15 is a robust circuit breaker engineered for reliable motor protection. It belongs to the SIRIUS 3RV2 series and is built to handle demanding industrial applications.
This circuit breaker is characterized by its size S2 and a thermal magnetic trip mechanism. It offers an adjustable current response range of 9.5 to 14 Amps, with a nominal operational current of 14A at 400V AC-3 and AC-3e. The device supports a wide operating voltage range from 20 to 690V, with a maximum rating of 690V for AC-3 and AC-3e applications. Its breaking capacity is rated at 100 kA at 400V.
Key electrical features include a 3-pole configuration and an operating frequency of 50-60 Hz. The breaker is equipped with transverse auxiliary switches, providing 1 normally open (NO) and 1 normally closed (NC) contact for signaling or control purposes. It also includes phase failure detection for enhanced safety.
Designed for easy installation, the 3RV20324SA15 mounts on a standard DIN rail. It operates reliably within an ambient temperature range of -20°C to +60°C and has a mechanical and electrical endurance of 50,000 switching cycles. The ATEX certification (Ex II (2) GD) indicates its suitability for use in potentially explosive atmospheres.
