SENTRON 3VA2 with ETU550 — 63 A line protection
Breaking capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so the same frame covers high-fault industrial mains and lower-fault distribution without a frame-size jump.
Rated 63 A straight through 50 °C; above that the ETU550 derates linearly — 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, 53.6 A at 70 °C. Footprint is 105 mm wide × 181 mm tall × 86 mm deep — standard 3-pole MCCB envelope for a 400 A frame. Front IP40, so it lives inside a closed enclosure, not exposed washdown.
Auxiliary contacts and communication
Communication function is onboard, so it can report status to a higher-level system without an add-on module.
