What this MCCB does for your line
The Siemens SENTRON 3VA2220-7MN32-0HH0 is a 3-pole molded case circuit breaker rated at 200 A continuous — flat across the ambient range from 40 °C to 70 °C, so no derating curve to track when the panel runs hot. It clears faults up to 330 kA at 240 V, 242 kA at 415 V, and 187 kA at 500 V, which gives you headroom for high-fault industrial distribution.
Panel integration
The 86 mm depth keeps it clear of gland plates and busbar covers in shallow enclosures.
SCCR and selectivity
At 690 V the rating drops to 5.2 kA, so this is not a 690 V primary breaker; it belongs on a 240–500 V system where it delivers full selectivity headroom.
