This Siemens 3VA5111-1MU31-0AA0 is a molded-case circuit breaker from the 3VA5 series, specifically designed for starter protection applications. It features a 3-pole configuration and a permanent rated current of 110A, with operational current ratings varying based on ambient temperature, down to 96.2A at 70°C.
The breaker is built to withstand significant electrical stresses, offering a maximum breaking capacity (Icu) of 150 kA at 240V and 70 kA at 415V. Its operational short-circuit current capacity (Ics) is also rated at 150 kA at 240V and 70 kA at 415V. The short-circuit current making capacity (Icm) is 330 kA at 240V and 154 kA at 415V.
With a rated insulation voltage of 800V and a maximum operational voltage of 690V AC, this circuit breaker is suitable for various industrial environments. It has a mechanical service life of typically 15,000 switching cycles and electrical endurance ratings that vary with voltage and load conditions. The unit is designed for DIN rail mounting and has a protection class of IP40 on the front.
Environmental conditions for operation range from -25°C to 70°C, with storage temperatures from -40°C to 80°C. The breaker is compliant with RoHS3 standards and has an MSL rating of 1.
