Rated 50 A continuous at 40 °C ambient, it holds that same 50 A rating up through 50 °C, then derates to 49 A at 55 °C and 45 A at 70 °C — so in a warm panel you lose very little headroom until you cross 55 °C. Interrupting capacity is 52.5 kA at 240 V, dropping to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V — that 7.5 kA floor at 690 V tells you this is a 240/415 V distribution breaker, not a 690 V motor-circuit device.
What the auxiliary configuration means for panel integration
No undervoltage release fitted, no ground-fault monitoring module, no communication function — this is a plain line-protection MCCB with the basic remote-control options. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — standard 3-pole MCCB footprint for a 50 A frame, fits most distribution panelboards without a width surprise.
How it compares to the 100 A frame sibling
The closest functional sibling in the same SENTRON 3VA family is the 3VA1110-5ED36-0AC0, which is a 100 A frame on the same 3-pole platform — same 70 mm depth, same auxiliary switch options, but physically wider and heavier to handle the higher continuous current. If your BOM calls for 50 A line protection with shunt trip and alarm contacts, this 3VA1050-2ED36-0HH0 is the correct frame — the 100 A sibling would work electrically but overshoots the ampacity and takes more panel width.
