The Siemens 3VA1163-5ED32-0DH0 is a 3-pole IEC frame 160 molded case circuit breaker rated for 63 A continuous current with a fixed thermal-magnetic trip unit (TM210). Its interrupting capacity hits 55 kA at 415 V AC — breaking capacity class M — which means it can clear high-fault currents on a 400 V industrial distribution bus without cascading upstream. The part ships with a factory-fitted undervoltage release (UVR) for 208–230 V AC, two auxiliary switches (HQ), and one trip alarm switch (HQ), plus a nut keeper kit for the mounting hardware.
Mounts on a standard DIN rail or panel-mount via the supplied nut keeper kit. The 3VA1 frame footprint is shared across the 3VA1 series, so panel cutouts and busbar connections are consistent if you swap ratings. The UVR coil draws from the 208–230 V AC control circuit; verify the control transformer sizing if you are adding this to an existing panel.
