What this 200 A MCCB actually delivers
The Siemens SENTRON 3VA1220-4GF42-0DC0 is a 4-pole molded case circuit breaker rated for 200 A continuous at 40 °C, with a 70 mm depth, 140 mm width, and 158 mm height that fits standard panel layouts. The 200 A rating holds through 50 °C — no derating needed up to that point — then steps down to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C, so you can size the breaker for a 200 A bus and still get full capacity in a ventilated enclosure. At 240 V it interrupts 121 kA; at 415 V it handles 75.6 kA; at 440 V it's 52.5 kA; at 500 V it's 17 kA; and at 690 V it's 11.9 kA.
What the approvals tell you
The SENTRON 3VA series carries UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications, so it's accepted in North American and IEC panels without a separate evaluation.
