Construction and auxiliary wiring
The 3VA1112-6GF46-0KF0: This 4-pole MCCB carries a TM240 thermal-magnetic overcurrent release — the thermal element handles overloads, the magnetic element handles short-circuits. It includes a shunt trip (STL) for remote tripping, plus one auxiliary switch and one trip alarm switch (HQ configuration). The integrated auxiliary trip order code is 3VA9688-0BL33. No undervoltage release, no ground-fault monitoring, no communication module. Front protection is IP40, so it's suited for clean indoor panels; not rated for washdown. Width is 4 in, height 130 mm — verify your DIN-rail or mounting-plate layout against those dimensions before committing the BOM line.
