The Siemens 3VA6210-5KM31-2AA0 is a high-performance molded-case circuit breaker from the SENTRON series, designed for robust system protection. This 3-pole breaker operates at a rated voltage of 690V and has an operational current of 100A, maintaining this rating across temperatures from 55°C to 70°C.
It offers significant breaking capacity, rated at 35kA according to UL 489 at 480V, and 55kA according to IEC 60947 at 415V. The breaker is equipped with an ETU830 electronic trip unit featuring LIG protection, with adjustable settings for overload (Ir: 40A-100A), short-circuit (Ii: 1.5-12 x In), and ground-fault (Ig: 0.2-1 x In, tg: 0.05-0.8s).
Designed for convenient installation, it features DIN rail mounting and a lever actuator. The breaker also includes communication and other measurement functions. Its mechanical service life is typically 20,000 switching cycles, with electrical endurance varying by voltage and load conditions.
