Product FAQs

6 answers
Which legacy Siemens breakers does the 3VA5180-4EC31-0AA0 replace?

This 3VA51 frame breaker is the modern replacement for legacy 80A ED-frame models like the ED43B080 and NGG-frame models like the NGG3B080L. When installing it in existing P1 or P2 panelboards, a specific mounting adapter kit is required.

What panelboards are compatible with the 3VA5180-4EC31-0AA0?

This breaker is designed for direct installation in Siemens 3VA panelboards and switchboards. It can also be installed in Siemens P1 and P2 panelboards when equipped with the appropriate retrofit mounting adapter.

What is the physical frame size of the 3VA5180-4EC31-0AA0?

This breaker is built on the Siemens 3VA51 frame platform, which has a maximum physical capacity of 125A. This specific unit is factory-calibrated for a maximum continuous current of 80A.

Can the trip settings on the 3VA5180-4EC31-0AA0 be adjusted in the field?

Yes, this breaker features a TM230 thermal-magnetic trip unit with an adjustable magnetic (instantaneous) setting. This allows you to fine-tune the short-circuit response for system coordination, while the thermal (long-time) overload setting remains fixed at 80A.

Is the 3VA5180-4EC31-0AA0 suitable for reverse feeding?

Yes, Siemens 3VA5 molded case circuit breakers are HACR rated and suitable for reverse feed applications, providing flexibility in power distribution layouts.

How do I order this breaker with factory-installed standard lugs?

The base 3VA5180-4EC31-0AA0 catalog number is typically supplied without lugs for use with busbar connections or nut keepers. To order the same 80A breaker with factory-installed standard line and load lugs, the 12th digit of the catalog number changes to a 6, making it 3VA5180-4EC36-0AA0. Alternatively, you can purchase field-installable lug kits separately.
