Siemens SENTRON 3VA2220-5MN32-0HH0 — Motor Protection MCCB
Interrupting capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 5.2 kA at 690 V — the steep drop at 690 V means this breaker is best applied on 400 V class systems where its full fault-clearing capability is available.
The width is the critical panel cutout dimension; verify busbar and adjacent device spacing against the 105 mm pole pitch. Maximum power dissipation is 46 W, which should be factored into enclosure thermal calculations, particularly in sealed or high-ambient cabinets.
For BOM freeze or qualification projects, the manufacturer's change-control process applies; documented compliance (RoHS, REACH, UL, IEC) is part of the SENTRON series standard documentation package.
