Product FAQs
7 answersWhat type of trip unit is installed in the 3VA5270-6EF31-0AA0?
This breaker features a TM240 ATAM (Adjustable Thermal, Adjustable Magnetic) trip unit. The thermal overload protection (Ir) is adjustable from 56A to 70A, and the magnetic short-circuit protection (Ii) is adjustable from 350A to 700A.
Which Siemens panelboards are compatible with this circuit breaker?
The 3VA5270-6EF31-0AA0 is designed for use in Siemens P1, P2, and P3 panelboards, as well as SB switchboards and Motor Control Centers. Proper installation requires the correct branch strap kits or mounting hardware specific to the 250A 3VA52 frame.
Can the 3VA5270-6EF31-0AA0 be used for reverse feed applications?
Yes, all Siemens 3VA5 thermal-magnetic molded case circuit breakers are UL listed for reverse feed applications, allowing them to be safely back-fed.
What legacy Siemens circuit breaker does the 3VA5270-6EF31-0AA0 replace?
This 3VA52 frame breaker provides a direct upgrade path for legacy Siemens FD-frame breakers, such as the HFD63B070, offering modern protection capabilities in a similar footprint.
What is the maximum frame size capacity for this breaker?
While this specific unit is factory-configured with a 70A continuous current rating, it is built on the Siemens 3VA52 frame, which has a maximum physical capacity of 250A.
What wire sizes are supported by the standard lug kits for the 3VA52 frame?
When equipped with standard Siemens 3VA9233-0JB12 aluminum lug kits, the 3VA52 frame accepts wire sizes ranging from 6 AWG to 350 kcmil. Copper-only box terminals (such as the 3VA9233-0JA12) accept 4 AWG to 350 kcmil.
Does the 3VA5270-6EF31-0AA0 provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic circuit breaker designed for line protection against overloads and short circuits. It does not feature integrated ground fault or arc fault capabilities.
