Rated continuous current Iu is 100 A, and it holds that rating from 40 °C through 50 °C ambient without derating; at 55 °C it still carries 96 A, and at 70 °C it's 90 A — so in a warm enclosure you lose less than 10 % of the nameplate. Breaking capacity is the headline: 330 kA at 240 V AC, 242 kA at 415/440 V, 187 kA at 500 V, and 52.5 kA at 690 V.
Trip unit, auxiliary contacts, and releases
The overcurrent release is an ETU310M — an electronic trip unit with adjustable thermal and magnetic settings, plus a trip indicator and voltage trigger capability. That voltage trigger (shunt trip STL) lets a safety PLC or E-stop circuit open the breaker remotely without running power through the main contacts. The base switch itself is order code 3VA2110-7MS36-0AA0, and the integrated auxiliary trip module is 3VA9688-0BL33. If you need those, you're looking at a different 3VA2 option.
Maximum power loss is 75 W — not negligible; if you're packing several of these in a sealed enclosure, you'll need to account for the heat in the thermal budget.
