This Siemens 3VA5225-5GC41-0AA0 is a 4-pole molded-case circuit breaker from the SENTRON 3VA5 series, designed for system protection applications. It features a robust construction with a 250A permanent rated current (Iu) and a maximum operational voltage of 690V AC.
The circuit breaker provides a breaking capacity of 35kA at 480V according to UL 489 standards, and 55kA at 415V according to IEC 60947. The overload protection is set by Ir=250A, with fixed short-circuit protection (Ii) adjustable from 5 to 10 times the rated current. It also includes 100% N-conductor protection.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V, this breaker is built for durability. It is designed for DIN rail mounting and features a lever actuator.
Key electrical specifications include an insulation voltage (Ui) of 800V and a maximum power loss of 58W. The operational current is maintained at 250A up to 50°C, gradually decreasing to 220A at 70°C.
