Siemens 3VA6340-6HL31-0AA0 Molded Case Circuit Breaker

No. The -0AA0 suffix in the catalog number indicates this breaker is shipped without lugs. If you are wiring it with standard cables, you will need to purchase the appropriate lug kits separately or order the breaker with lugs factory-installed.

Yes. While the 3VA6340-6HL31-0AA0 ships without lugs, you can order the identical breaker configuration with factory-installed standard aluminum lugs by using catalog number 3VA6340-6HL36-0AA0.

If you install the standard single-cable aluminum lugs (such as Siemens part number 3VA9373-0JB13), the terminals will accept one 1 AWG to 600 kcmil copper or aluminum wire per phase.

The LI code indicates the electronic trip unit provides adjustable Long-Time (L) overload protection and adjustable Instantaneous (I) short-circuit protection. It does not include Short-Time or Ground Fault settings.

The Long-Time pickup (Ir) can be adjusted from 160A to 400A. The Instantaneous short-circuit pickup (Ii) is adjustable from 1.5 to 10 times the continuous current rating, which equates to a range of 600A to 4000A.

As a standard feed-thru molded case circuit breaker, it can be mounted in Siemens P3, P4, and P5 panelboards, as well as Siemens switchboards and Motor Control Centers (MCCs) using the proper mounting hardware.

Yes, the ETU320 LI trip unit has a permanently active thermal memory that cannot be deactivated. This function tracks previous thermal history to prevent the breaker from being reset into an existing overload condition before the downstream circuit has adequately cooled.
