This Siemens 3RV20314UA15 is a size S2 circuit breaker specifically designed for motor protection applications. It features a thermal magnetic overload release with an adjustable current response value ranging from 32 to 40 A, and a trip class of CLASS 10. The breaker has 3 poles and supports a rated operating voltage of up to 690 V.
With a breaking capacity of 65 kA at 400 V, this circuit breaker ensures reliable protection against short circuits. It includes transverse auxiliary switches with 1 NO and 1 NC contacts, suitable for various control and signaling functions. The device is designed for DIN rail mounting and operates within an ambient temperature range of -20 to +60 °C.
Key electrical characteristics include an operational current of 40 A at AC-3 and AC-3e at 400 V, and a power loss of 20 W at AC in hot operating state. The mechanical service life for both main and auxiliary contacts is a typical 50,000 switching cycles.
