Product FAQs
9 answersWhat type of electronic trip unit is installed in the 3VA6816-6HQ31-0AA0?
This breaker features the Siemens ETU360 trip unit. It delivers LSIG protection (Long-Time, Short-Time, Instantaneous, and Ground-Fault) via rotary dials for precise field adjustments, but does not include an LCD screen.
What is the adjustable continuous current range for the 3VA6816-6HQ31-0AA0?
The long-time overload protection (Ir) can be dialed down from the maximum 1600A frame rating to as low as 600A, allowing flexibility for various load sizes.
How adjustable are the short-circuit protection settings on this 1600A breaker?
The short-time delay pickup (Isd) can be set between 1.5 and 10 times the rated current. The instantaneous pickup (Ii) provides a selectable range of 1.5 to 7.5 times the rated current.
Can the 3VA6816-6HQ31-0AA0 be applied in 100% rated continuous duty applications?
No, this specific model is a standard 80% rated breaker, indicated by the 0 in the 13th digit of the catalog number (-0AA0). For a 100% rated version, you must order the alternate catalog number ending in -2AA0.
What does the H in the 3VA6816-6HQ31-0AA0 catalog number mean?
