Product FAQs
6 answersWhat Siemens panels are compatible with the 3VA4112-4ED34-0AA0?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens switchboards. It mounts directly to the panel bus rather than using a plug-in or DIN-rail connection.
Does this breaker include lugs for both the line and load sides?
No. Because the line side is designed to bolt directly to the panelboard bus, the 3VA4112-4ED34-0AA0 is supplied with factory-installed lugs on the load side only.
What wire sizes and materials are supported by the load lugs?
The factory-installed load lugs accept 8 AWG through 3/0 AWG conductors. They are rated for both copper (Cu) and aluminum (Al) wiring, providing flexibility for different installation requirements.
What does the "LI" trip function mean on this Siemens breaker?
The LI code indicates the TM210 thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip thresholds are fixed and cannot be field-adjusted.
Can the 3VA4112-4ED34-0AA0 be used in DC applications?
Yes, in addition to alternating current circuits, this thermal-magnetic breaker is certified for direct current systems up to 250V DC, where it delivers a 65 kA interrupting capacity.
What does the "Class S" designation indicate for this breaker?
Class S indicates this breaker features the standard breaking capacity for the Siemens 3VA41 frame series, which provides a 25 kA interrupting rating at 480V AC and 14 kA at 600Y/347V AC.
