Breaking capacity across voltages
The 3VA2110-6HN36-0JA0: The interrupting rating drops as line voltage rises: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V. That 5 kA at 690 V is the hard ceiling — if your panel feeds a 690 V bus with fault current above that, this breaker is not the right choice. For 400 V class systems the 187 kA figure covers most industrial service entrances and large motor control centers.
Thermal derating and operating range
Rated 100 A from 40 °C up to 50 °C without derating. Above that the curve steps down: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. If your enclosure runs hot — say a non-ventilated panel near a furnace line — factor that 85 A floor at 70 °C into your load schedule. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Trip unit and auxiliary options
The ETU350 overcurrent release is an electronic trip unit with adjustable long-time, short-time, instantaneous, and ground-fault protection (ground-fault monitoring is not fitted on this variant — order code suffix 0JA0 means without). The integrated shunt trip (STL) is a separate release coil that opens the breaker on a control signal; its order code is 3VA9688-0BL32. No auxiliary contacts, no undervoltage release, no communication module on this build. If you need remote status or a UVR, you are looking at a different 3VA variant.
