The Siemens 3RV20314SB15 is a size S2 circuit breaker from the SIRIUS product line, specifically designed for motor protection applications. It features a thermal magnetic overload release with an adjustable current response value ranging from 9.5 to 14 A.
This 3-pole circuit breaker operates at a rated voltage of up to 690 V and has an operational current of 14 A at AC-3 and AC-3e at 400 V. It provides a breaking capacity of up to 100 kA at 240 V and 65 kA at 400 V. The device includes a transverse auxiliary switch with 1 NO and 1 NC contacts.
With a mechanical and electrical endurance of typically 50,000 switching cycles, the 3RV20314SB15 is built for reliability. It operates within an ambient temperature range of -20 to +60 °C and is suitable for installation at altitudes up to 2,000 meters. The breaker is designed for DIN rail mounting and features a rotary actuator.
Key protective functions include phase failure detection and a CLASS 20 trip class. The power loss at AC in hot operating state is 12.5 W. This circuit breaker is compliant with RoHS3, REACH Unaffected, and MSL 1 standards.
