It's a line-protection device — no ground-fault monitoring, no undervoltage release, no auxiliary contacts — built for straightforward overcurrent and short-circuit protection in distribution panels. Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V. The 200 A rating holds flat from 40 °C through 50 °C, then derates to 176 A at 70 °C, so panel ambient temperature matters for sizing.
The 4-pole frame takes up 140 mm width on the rail, with a 158 mm height and 70 mm depth — check your enclosure depth before committing. Front IP40 protection means it's splash-safe from the front but not sealed; keep it inside a cabinet for washdown environments. The shunt trip (order code 3VA9688-0BL32 for the release itself) allows remote tripping via a control signal, useful for emergency-stop circuits or load-shedding schemes.
