The interrupting rating drops as line voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Rated current holds flat at 100 A from 40 °C up to 50 °C, then steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power dissipation is 25 W, which factors into the enclosure thermal budget.
Shunt trip and auxiliary release
The undervoltage release is absent on this order code, so it will not drop out on a voltage dip; if that behavior is needed for your safety circuit, a different 3VA variant with the undervoltage release is the correct pick.
The 4-pole width (101.6 mm) is standard for a 100 A frame in the SENTRON 3VA platform — it occupies the same mounting footprint as other 4-pole 3VA breakers in the same frame size, so a panel laid out for a 3VA11 or 3VA10 with the same pole count should accept this unit without re-drilling the backplate.
