Product details

SENTRON 3VA1140-4EF36-0HH0 — 40 A MCCB for Line Protection

It carries a 40 A rating at 40 °C ambient, with a slight derating curve: still 40 A at 45 °C, 39 A at 55 °C, 38 A at 65 °C, and 37 A at 70 °C — so in a warm panel you lose about 3 A off the top end. Breaking capacity is substantial: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Integration Notes

The shunt trip allows remote tripping via a control signal — useful for emergency-stop circuits or undervoltage protection schemes.
