It's built for line protection duty — the kind of main feeder or heavy branch breaker you'd spec into a distribution panel where fault current is serious. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and still 17 kA at 690 V. That means it can interrupt a massive fault without the arc blowing upstream — critical for transformer-secondaries or high-capacity bus risers where a smaller MCCB would cascade-fail. The 200 A rating holds flat from 40 °C to 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.
It'll drop into a DIN-rail or screw-mounted panel layout without re-drilling if you're swapping from another 3VA frame.
