SENTRON 3VA1080-3ED42-0JH0 — 80 A MCCB with TM210 release and shunt trip
The integrated shunt trip (STL) allows remote tripping via a control signal, useful for emergency-stop or supervisory shutdown circuits.
Breaking capacity varies sharply with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. Thermal derating is minimal up to 50 °C — the breaker carries the full 80 A at 40, 45, and 50 °C. Above that it steps down: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. In a hot panel near drives or transformers, that 72 A at 70 °C is the real-world limit, not the nameplate 80 A.
