The Siemens 3RV20214CA25 is a robust circuit breaker from the SIRIUS 3RV2 series, specifically engineered for motor protection applications. This device operates with a thermal magnetic trip mechanism and offers an adjustable current response value ranging from 16 to 22 Amperes.
With a rated operational current of 22A and a maximum operating voltage of 690V, this circuit breaker is suitable for demanding industrial environments. It provides a breaking capacity of 100 kA at 240V AC and includes essential protective functions such as phase failure detection. The unit is designed for DIN rail mounting and comes with transverse auxiliary switches, including 1 normally open (NO) and 1 normally closed (NC) contact.
Key technical specifications include a trip class of CLASS 10, a power loss of 10.5W, and an insulation voltage of 690V. The ambient temperature range for operation is -20 to +60°C. The circuit breaker also meets ATEX directive requirements, indicated by its Ex II (2) GD protection type and DMT 02 ATEX F 001 certification.
This component is built for reliability with a mechanical and electrical endurance of typically 100,000 switching cycles. Its compact size S0 and DIN rail mounting facilitate easy integration into control panels and electrical systems.
