The Siemens SENTRON 3VA2325-5HL32-0AH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current, designed for line protection in distribution panels. Its 250 A rating holds steady across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel layout in warm enclosures.
Breaking capacity reaches 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 7.5 kA at 690 V. That 187 kA at 240 V gives plenty of headroom for high-fault panels; the 121 kA at 415 V still covers most industrial service-entrance applications. The adjustable trip range spans 375 A to 3 000 A, so the breaker can be set for downstream coordination without swapping the frame.
