Product FAQs
8 answersWhat frame size does the Siemens 3VA6440-5JQ31-2AA0 use?
This breaker is built on the Siemens 3VA64 frame. While the frame itself has a maximum capacity of 600A, this specific unit is factory-configured with a 400A maximum continuous current rating.
Which specific electronic trip unit is installed in the 3VA6440-5JQ31-2AA0?
It features the Siemens ETU560 trip unit, which includes an integrated LCD screen for precise configuration of the Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) protection parameters.
What is the adjustable range for the long-time trip setting on this breaker?
The ETU560 electronic trip unit allows the long-time continuous current pickup (Ir) to be adjusted from 160A to 400A, which corresponds to 0.4 to 1.0 times the nominal current rating.
What are the short-time and instantaneous pickup ranges for this 400A breaker?
The short-time pickup (Isd) is adjustable from 0.6 to 10 times the rated current. The instantaneous pickup (Ii) can be set from 1.5 to 12 times the rated current.
Does the 3VA6440-5JQ31-2AA0 provide adjustable ground-fault protection?
Yes, the integrated LSIG trip unit includes ground-fault protection (Ig) that is adjustable from 0.2 to 1.0 times the rated current, with adjustable time delays (tg) ranging from 0.05 to 0.8 seconds.
What breaking capacity class does the 3VA6440-5JQ31-2AA0 fall under?
This breaker is classified as a Class M (Medium) breaking capacity device within the 3VA series. This designation corresponds to its interrupting ratings of 35kAIC at 480V and 18kAIC at 600V.
Can this 3-pole breaker provide neutral conductor protection in a 4-wire system?
Yes, the ETU560 trip unit supports neutral conductor protection when paired with an external neutral current transformer. This allows for neutral protection up to 160 percent of the rated current.
Which Siemens distribution equipment is this 400A breaker compatible with?
The 3VA6440-5JQ31-2AA0 is designed for installation in Siemens P4 and P5 panelboards, as well as compatible Siemens switchboards and motor control centers.
