Its interrupting capacity hits 220 kA at 240 V — that's the number that governs selectivity in a high-fault panel; at 415 V it still delivers 154 kA, and at 690 V it's 17 kA. No auxiliary contacts or communication module onboard — this is a standalone breaker for a main feeder or large branch.
Derating and temperature
It starts to derate at 55 °C to 48 A, then 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
Width is 76.2 mm (about 4.5 modules of 17.8 mm) — standard for a 3-pole 50 A frame. Depth 70 mm, height 130 mm.
Listed as current production. The undervoltage release is a separate order code (3VA9608-0BB11) that ships with the breaker — verify it's included in your BOM. No official successor or cross-reference; this is the active SENTRON 3VA line.
