Siemens 3VA2010-6HL46-0AA0 — 100 A SENTRON MCCB with ETU320
That 100 A holds at every 5 °C step, so it's a straight 100 A breaker for most panel environments. The trip range is adjustable between 150 A and 1 200 A — that's the short-circuit and overload pickup window, not the continuous rating. The 100 A continuous frame stays fixed; the ETU320 lets you dial the magnetic/instantaneous threshold within that band to coordinate with downstream devices. Interrupting capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.
Peer comparison — 3VA1110-5ED36-0AA0
The closest functional sibling in the SENTRON family is the 3VA1110-5ED36-0AA0. Both are 4-pole MCCBs with electronic trip units, but the 3VA1110 frame is physically smaller and rated for lower interrupting capacities. The 3VA2010-6HL46-0AA0 carries the higher SCCR (242 kA vs the 3VA1110's typical 65-100 kA range at 240 V) and the wider trip adjustment band. If your panel was specified around a 3VA1110, the 3VA2010 will not drop in without checking the mounting footprint — the 3VA2010 is taller and deeper. Rewiring is not the issue; the bus-bar and enclosure cutout dimensions differ.
