Product FAQs
7 answersWhat are the thermal and magnetic adjustment ranges for the 3VA5210-5EF31-0AA0?
This breaker features a TM240 ATAM trip unit. The continuous thermal protection is adjustable from 80A to 100A. The instantaneous magnetic protection is adjustable from 500A to 1000A, which is 5 to 10 times the nominal current rating.
What frame size does the 3VA5210-5EF31-0AA0 circuit breaker use?
This 100A breaker is built on the Siemens 3VA52 frame, which has a maximum capacity of 250A. It shares the same physical dimensions and accessory compatibility as other 3VA52 frame breakers.
Which Siemens panelboards are compatible with the 3VA5210-5EF31-0AA0?
This 3VA52 frame breaker is designed for installation in Siemens P2 and P3 panelboards, as well as compatible switchboards and standalone enclosures.
Can the Siemens 3VA5210-5EF31-0AA0 be reverse fed?
Yes. All Siemens 3VA5 thermal-magnetic trip circuit breakers are UL listed for reverse feed applications, allowing line power to be connected to either the top or bottom terminals.
How should this 3-pole breaker be wired for high voltage DC applications?
This breaker is rated for up to 750VDC. When applying three-pole breakers on 500V or higher ungrounded DC systems, the power supply must be connected in a series zig-zag configuration through the breaker poles to ensure voltage is uniformly distributed.
What wire sizes are supported by the lug kits for the 3VA52 frame?
Wire capacity depends on the specific lug kit installed. Common compatible kits for the 3VA52 frame include the 3VA9233-0JG11, which accepts 14 AWG to 1/0 AWG copper or aluminum wire, and the larger 3VA9233-0JG12, which accepts 6 AWG to 350 kcmil wire.
Does the 3VA5210-5EF31-0AA0 include ground fault or arc fault protection?
No. This specific model features a standard thermal-magnetic trip unit for overload and short-circuit protection. It does not include integrated ground fault or arc fault protection functions.
