Siemens 3VA5215-7ED31-0AA0 Molded Case Circuit Breaker

This breaker installs directly into Siemens 3VA panelboards and switchboards. It can also be installed in standard P1, P2, and P3 panelboards, but you must use the appropriate Siemens mounting adapter kit designed for 3VA frames.

The LI code specifies a thermal magnetic trip unit providing fixed Long-Time (L) overload protection and fixed Instantaneous (I) short-circuit protection. It does not include adjustable dials for short-time or ground fault settings.

Yes, it supports DC applications up to 750VDC with a 100kA interrupting rating. When installing in a DC system, ensure your wiring configuration aligns with the specific series-pole requirements for high-voltage DC switching.

The 3VA series is the modern global platform replacing legacy Siemens frames like the ED and FD series. However, because the physical dimensions and mounting footprints differ, you cannot swap them directly without a specific retrofit kit or panel adapter.

This feed-thru breaker is configured for lug terminations. When terminating conductors, always verify the approved wire gauge range and torque specifications printed directly on the breaker faceplate or lug body to ensure a secure, code-compliant connection.

This breaker is rated to safely clear faults up to 100kA at 480VAC. Before installation, a licensed electrician or engineer must verify that the available short-circuit current at the panel does not exceed this threshold, unless it is being applied as part of a tested series-rated combination.
