What this 3VA MCCB delivers
Rated 100 A continuously at 40 °C, it holds that rating through 50 °C before a slight derate curve kicks in — 98 A at 55 °C, 96 A at 60 °C, down to 91 A at 70 °C. Short-circuit interrupting capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. That's a high-fault rated MCCB — it clears serious energy without upstream coordination headaches, assuming the rest of the selective chain is specced to match. It's a straight line-protection breaker: feed it, protect the cable, trip on overload or short-circuit.
Integration notes
Power loss at full rated current is 25 W maximum.
