This Siemens 3VA5220-5EC31-1AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, designed for system protection. It has a rated current (In) of 200A and an overload protection setting (Ir) of 200A. The fixed short-circuit protection (Ii) ranges from 5 to 10 times the rated current.
The circuit breaker offers a breaking capacity of 35kA at 480V, 85kA at 240V, and 18kA at 600V. It operates with an overcurrent release type TM230 and features LI protection function. The device is rated for a maximum operational current of 250A (frame size) and supports DIN rail mounting.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance of 8,000 cycles at 480V, this breaker is built for durability. It has a maximum power loss of 42.5W and an active power loss per pole of 14.17W under AC hot operating conditions. The operating temperature range is from -25°C to 70°C, with storage temperatures from -40°C to 80°C. The front protection class is IP40.
Additional features include HACR Type designation and UL 489 SB (naval) compliance. It does not have communication or other measurement functions. The dimensions are 185mm height, 105mm width, and 83mm depth.
