Siemens 3VA1096-3ED32-0AF0 — SENTRON MCCB, 16 A, 75.6 kA
Rated 16 A continuously at 40 °C across all three poles, it holds that rating through 55 °C and derates to 15 A at 60 °C and above — so in a warm enclosure you lose one amp, not the whole device. Breaking capacity is 75.6 kA at 240 V, stepping down to 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That means on a 480 V system you get the 440 V figure (32 kA) as the closest — enough for most commercial panelboards but verify against your available fault current.
The auxiliary switch configuration (1 auxiliary + 1 trip alarm switch HQ) occupies the accessory slot.
