This Siemens 3RV23314KC10 is a motor protection circuit breaker from the SIRIUS 3RV2 series. It is designed for starter combinations and features a size S2 rating with a nominal operational current of 73A at AC-3, 400V. The breaker operates with a magnetic trip mechanism and is suitable for mounting on a DIN rail.
With a rated operating voltage range of 20 to 690V and a frequency rating of 50 to 60 Hz, this circuit breaker provides robust protection. It offers a breaking capacity (Icu) of up to 100 kA at 240V and 65 kA at 400V. The device has a mechanical and electrical endurance of typically 20,000 switching cycles.
Environmental conditions for operation include an ambient temperature range of -20 to +60 °C and a relative humidity of 10 to 95%. The circuit breaker is built to withstand shock resistance according to IEC 60068-2-27 (25g / 11 ms) and can be installed at altitudes up to 2,000 meters.
Key electrical specifications include a power loss of 29.5W in hot operating state and a surge voltage resistance of 6 kV. It also provides full-load current ratings for 3-phase AC motors, such as 65A at 480V and 62A at 600V, along with corresponding horsepower ratings.
