The Siemens 3RV20210HA15 is a robust circuit breaker engineered for reliable motor protection. It belongs to the SIRIUS 3RV2 series and is built with a thermal magnetic trip mechanism.
This breaker has a size S0 frame and 3 poles, suitable for applications requiring precise current control. The adjustable current response value for overload protection ranges from 0.55 A to 0.8 A, with a fixed N-release of 10 A. It operates at a rated voltage of up to 690 V and supports a frequency of 50 to 60 Hz.
Key protective features include phase failure detection and a CLASS 10 trip class. The breaker is designed for DIN rail mounting and includes transverse auxiliary switches with 1 normally open (NO) and 1 normally closed (NC) contact. Its mechanical and electrical endurance is rated for a typical 100,000 switching cycles.
Environmental specifications include an operating temperature range of -20 to +60 °C and an installation altitude limit of 2,000 m. The breaker also meets ATEX directive requirements for use in potentially explosive atmospheres.
