What this MCCB carries and where it fits
The Siemens SENTRON 3VA1110-4EF36-0CC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, holding that rating all the way to 50 °C before it starts to derate — 96 A at 55 °C, 90 A at 70 °C. The TM240 thermal-magnetic release handles overload and short-circuit protection in one package, and the included undervoltage release lets you drop the breaker on loss of control voltage. Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and still 11.9 kA at 690 V — so it's sized for high-fault industrial service, not light commercial.
Panel fit and wiring note
Front face is IP40 — fine for a clean indoor panel, but not washdown. Depth is 70 mm, width 76.2 mm, height 130 mm, so it drops into a standard SENTRON 3VA footprint. The auxiliary contact version ships with 2 auxiliary switches HQ, and the integrated auxiliary trip is order code 3VA9608-0BB24 if you need to wire that separately. Spring-cage or screw terminals? The spec doesn't spell termination type, but the 3VA family typically accepts up to 70 mm² Cu cable on the line side — verify lug range against your wire when quoting.
