The 63 A rating holds flat from 40 °C through 50 °C, then derates to 60.6 A at 55 °C and 53.6 A at 70 °C. That 105 mm width is three pole spaces on a standard 35 mm DIN rail — it occupies the same footprint as a 3-pole frame from the 3VA1 or 3VA2 family, so a panel laid out for one of those accepts this unit without re-drilling the gland plate.
Auxiliary contacts and shunt trip — what is wired in
That is four discrete signal outputs for PLC status monitoring — no need to add a separate auxiliary contact block. The shunt trip (STL) release is also built in, so a remote trip signal from an E-stop or safety relay lands directly on the breaker without an external contactor. The integrated auxiliary trip (3VA9688-0BL32) and the supplied basic switch (3VA2163-7HN32-0AA0) are referenced on the nameplate. If you need to order a replacement auxiliary block, use those order codes — not the base breaker MPN.
The 3VA1110-5EE32-0JA0 is a smaller-frame MCCB (100 A frame, thermal-magnetic trip) from the same SENTRON family. The 3VA2163-7HN32-0JL0 uses a 250 A frame with an electronic trip unit, so it offers adjustable protection curves and higher interrupting capacity. Physically, the 3VA1110 is narrower (70 mm vs 105 mm) and shorter, so it does not drop into the same DIN-rail footprint without a new gland plate. If your BOM calls for the 3VA1110 and you are considering this as a substitute, verify the panel cutout and the trip curve requirements first.
