The Siemens 3VA6340-5KQ41-0AA0 is a 4-pole molded-case circuit breaker from the 3VA6 series, designed for system protection applications. This breaker has a rated current of 400A and an insulation voltage of 600V, with a maximum breaking capacity of 85kA at 240V according to IEC standards.
It features an ETU860 electronic trip unit with LSIG (Long-time, Short-time, Instantaneous, Ground-fault) protection functions. The overload protection is adjustable from 160A to 400A, and short-circuit protection is adjustable from 0.6 to 10 times the rated current (Isd) and 1.5 to 10 times the rated current (Ii). Ground fault protection is adjustable from 0.2 to 1 times the rated current with a time delay adjustable from 0.05 to 0.8 seconds.
This circuit breaker is suitable for HACR type applications and is mountable on a DIN rail. It also includes communication and other measurement functions. The mechanical service life is typically 15,000 switching cycles, with electrical endurance varying based on voltage and load conditions.
