This Siemens 3VA6225-5KP31-0AA0 is a molded-case circuit breaker from the 3VA6 series, designed for system protection. It is a 3-pole breaker with a rated operational current of 250A and a breaking capacity of 35kA at 480V, conforming to UL 489 standards. The breaker utilizes an ETU850 electronic trip unit with LSI (Long-time, Short-time, Instantaneous) protection functions.
Key electrical specifications include an insulation voltage of 600V and a maximum power dissipation of 42W. The mechanical service life is rated for a typical 20,000 switching cycles, with electrical endurance varying by voltage and load conditions. The breaker supports communication and other measurement functions.
Mechanically, the unit has dimensions of 198mm in height, 105mm in width, and 86mm in depth, designed for DIN rail mounting. It offers adjustable overcurrent response values for overload (Ir) from 100A to 250A and for short-circuit protection (Isd) from 0.6 to 10 times the rated current, with an instantaneous trip current (Ii) range of 1.5 to 10 times the rated current.
Compliance includes RoHS3, REACH Unaffected, and MSL 1. Approval agencies include CCC, CE, CSA, EAC, UL489, and VDE.
