Siemens 3VA2163-6HN32-0KC0 — 63 A MCCB with Shunt Trip, Line Protection
This breaker's interrupting rating is flat across the 240-415 V range: 242 kA at 240 V, 187 kA at 415 V and 440 V, then 121 kA at 500 V. That means it can sit in a hot top-of-panel location without losing capacity.
The 3-pole frame mounts via screw-clamp or plug-in base in a standard distribution board. The shunt trip (STL) is factory-integrated — no field-add kit needed. Two auxiliary switches (HQ) give you one N/O + one N/C contact for remote status. The breaker is line-protection configured (not motor-protection), so thermal-magnetic curve is set for cable and busbar protection, not overload relay coordination.
