It's rated for a continuous current Iu of 100 A, and the temperature derating is tight: it holds the full 100 A from 40 °C up through 50 °C, then steps down to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. That's a clean curve — you can push ambient to 50 °C without losing any ampacity, which matters in a crowded panel. The breaking capacity is the headline number here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V.
Release, auxiliaries, and what's inside the can
The overcurrent release is an ETU310M — that's an electronic trip unit with adjustable thermal and magnetic settings, typical for motor protection where you need to dial in the overload class and short-circuit pickup to match the motor full-load amps. The basic switch is order code 3VA2110-7MS32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL30 — useful to know if you're replacing just the trip unit or the aux block separately. Mechanical endurance is rated at 20,000 operations. Power dissipation maxes out at 75 W.
