Siemens SENTRON 3VA1110-3EF32-0HH0 — 100 A MCCB, Line Protection, Active Production
Breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — figures that govern selectivity coordination in a distribution panel. Current-carrying capability holds at 100 A up to 50 °C ambient, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C — the thermal curve a panel designer needs when packing breakers in a warm enclosure.
The 3VA1110-3EF32-0HH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a footprint that fits standard SENTRON 3VA mounting positions in a distribution board.
The integrated auxiliary trip is order code 3VA9688-0BL30. No undervoltage release, no phase failure detection, no communication module, and no ground-fault monitoring are present on this variant. A voltage trigger is included; the trip indicator confirms the breaker has opened on fault.
