Condition

3VA6340-6JQ31 protection package: This Siemens 3VA6 UL-frame breaker is configured for a 400-amp, three-pole feeder with an ETU560 electronic trip unit. The JQ31 code identifies LSIG protection rather than a basic thermal-magnetic trip.

3VA6340-6JQ31 specifications

  • Catalog stem: 3VA6340-6JQ31
  • Frame and current: 3VA6, 400A
  • Poles: Three
  • Maximum voltage class: 600VAC
  • Breaking capacity: 65kA at 480VAC
  • Trip unit: ETU560 with LSIG functions

Do not separate the suffix from the breaker

Siemens 3VA numbers encode interrupting class, trip unit, terminals, and options. The complete suffix—including any characters after JQ31—must match the one-line diagram and the physical nameplate.

Engineering review

Confirm voltage-specific interrupting capacity, trip settings, sensor/rating plug, lugs, accessories, mounting, and coordination study. Electronic-trip breakers should be commissioned and installed by qualified personnel using the Siemens documentation.

There is a $15 charge for delivery. Additional charges will be imposed by our couriers for delivery to remote areas, a surcharge may be levied to cover carriage to these areas.
