The Siemens 3RV20314SA10 is a robust circuit breaker designed for motor protection applications. It belongs to the SIRIUS 3RV2 series and is built to size S2 specifications.
This thermal magnetic breaker offers an adjustable current response value ranging from 9.5 to 14 A, with a rated operational current of 14 A at 400V AC-3. It supports a wide operating voltage range from 20 to 690 V, with a maximum rated voltage of 690 V for both AC-3 and AC-3e applications. The breaker is equipped with phase failure detection and has a CLASS 10 trip class.
Key electrical performance includes a maximum short-circuit breaking capacity (Icu) of 65 kA at 400 V and an operating short-circuit breaking capacity (Ics) of 30 kA at 400 V. The instantaneous short-circuit trip unit responds at 208 A. It also provides a full-load current rating of 14 A at 480 V for 3-phase AC motors.
Designed for reliable operation, the 3RV20314SA10 operates within an ambient temperature range of -20 to +60 °C and can be mounted on a DIN rail. It meets ATEX, CCC, CE, CSA, EAC, IECEx, UL, and VDE approval standards.
