This Siemens 3VA6210-5HM31-0AA0 is a 3-pole molded-case circuit breaker from the 3VA6 series, UL frame 250. It is designed for line protection with an ETU330 electronic overcurrent release and LIG protection function. The breaker has an operational current of 100A at temperatures up to 70°C and a maximum insulation voltage of 600V.
Key electrical specifications include a breaking capacity of 35kA at 480V (UL 489) and 55kA at 415V (IEC 60947). The adjustable overcurrent protection ranges from 40A to 100A for overload (Ir) and 1.5 to 12 times In for short-circuit (Ii). Ground-fault protection is also adjustable from 0.2 to 1 times In with tripping times of 0.1s or 0.3s.
Mechanically, the circuit breaker features a DIN rail mounting type and a lever actuator. Its dimensions are 198mm in height, 105mm in width, and 86mm in depth. The device has a typical mechanical service life of 20,000 switching cycles and significant electrical endurance ratings at various voltage levels.
