Product FAQs

6 answers
What legacy Siemens breaker does the 3VA5170-6EF31-0AA0 replace?

This 3VA5 series breaker serves as a modern replacement for legacy ED63B070 circuit breakers.

What are the adjustment ranges for the TM240 trip unit on this 70A breaker?

The TM240 ATAM trip unit features an adjustable thermal overload setting from 56A to 70A, and an adjustable instantaneous short-circuit setting from 350A to 700A.

Which Siemens panelboards are compatible with this 3VA51 frame breaker?

It is designed for direct installation in Siemens 3VA panelboards and switchboards. It can also be installed in legacy P1, P2, and P3 panelboards when using the appropriate mounting adapter kit.

What is the physical frame size of the 3VA5170-6EF31-0AA0?

It is built on the Siemens 3VA51 frame, which has a maximum continuous current capacity of 125A, though this specific unit is factory-configured with a 70A trip unit.

Can this breaker be used in DC applications?

Yes, the 3VA5170-6EF31-0AA0 is rated for up to 500V DC, making it suitable for specific direct current distribution systems alongside its standard AC ratings.

How does ambient temperature affect the continuous current rating?

The breaker provides a full 70A continuous current rating at 40 degrees Celsius. In higher ambient temperatures up to 70 degrees Celsius, the operational current is derated to maintain safe performance.
