The Siemens 3RV20314BA150BA0 is a specialized circuit breaker in the SIRIUS product family, designed for robust motor protection applications. This device features a thermal magnetic trip mechanism, providing reliable overload and short-circuit protection.
Key electrical specifications include a rated operating voltage of up to 690V AC, with a maximum operational current of 20A at AC-3 400V. The adjustable current response value for overload release ranges from 14A to 20A, and it operates with a Class 10 trip class. The breaker offers a significant breaking capacity, with a maximum short-circuit current (Icu) of 50 kA at 240V and 400V.
Designed for easy integration, the 3RV20314BA150BA0 features DIN rail mounting and a rotary actuator type. It includes transverse auxiliary switches with 1 NO and 1 NC contact for signaling and control purposes. The operating temperature range is -50 to +60 °C, making it suitable for various environmental conditions. This circuit breaker is compliant with RoHS3 standards.
