That 100 A holds flat through every temperature step in the evidence, so it's a genuine 100 A frame, not a derated 125 A. The interrupting ratings are substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.
Auxiliaries and trip accessories
That means you can remotely trip the breaker from a safety circuit or E-stop chain, and you get status feedback — open/closed and tripped — back to the PLC or annunciator panel. The auxiliary switch design is built into the breaker, not a field-add-on kit, so the wiring is already accounted for in the 86 mm depth × 105 mm width × 181 mm height envelope. No undervoltage release on this order code, and no ground-fault monitoring module. If you need UVR or GF protection, that's a different variant in the 3VA family. The supplied basic switch is 3VA20106HN360AA0, which is the internal switching mechanism — the complete breaker assembly is what ships.
Mounts in a standard panel or enclosure on a mounting plate — it is a molded case breaker, not a DIN-rail snap-on unit, so plan for bolt-down installation. Maximum power loss is 13.5 W, which is modest for a 100 A frame — ventilation in the enclosure is still advisable if other heat sources are nearby. For that, look at the 3VA2 with communication options.
