MCCB for line protection
At 690 V it still clears 17 kA, which keeps it viable in 690 V line-side applications with moderate fault levels. The 200 A rating holds flat from 40 °C to 50 °C ambient; derating starts at 55 °C (194 A) and drops to 176 A at 70 °C. For a panel running warm, that means no loss of headroom until the enclosure ambient crosses 50 °C.
Physical fit and auxiliaries
Footprint is 140 mm wide × 158 mm tall × 70 mm deep. The 140 mm width is standard for a 4-pole 200 A frame in the 3VA platform — it occupies the same panel cutout as other 3VA breakers in this frame class, so a panel laid out for a 3VA1010-2ED42-0AE0 will accept this unit without rewiring. Four high-quality auxiliary switches (HQ) are built in. No communication module, no voltage trip, no phase-failure detection — this is a clean breaker with just the aux contacts for status feedback.
