The TM240 thermal-magnetic trip unit handles overloads and short circuits with a fixed thermal curve and magnetic pickup; there's no electronic adjustability, so what you see on the nameplate is what you get for coordination studies. ## Breaking capacity — the real-world fault handling This MCCB carries a breaking capacity of 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The 690 V rating is notably lower, but that's typical for a 3-pole breaker on a line-to-line 690 V system; if your panel is 400 V class, the 75.6 kA number is the one that governs your SCCR compliance. ## Thermal derating — don't assume 100 A at 70 °C ambient At 55 °C it's 96 A, at 60 °C it's 94 A, at 65 °C it's 92 A, and at 70 °C it's 90 A. The trip unit itself is thermal-magnetic, so the thermal element is ambient-sensitive; the derating curve is the manufacturer's own data, not a rule-of-thumb. ## Panel fit and auxiliary contacts Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB width that fits most DIN-rail or screw-mount panel layouts.","metaTitle":"Siemens 3VA1110-4EF36-0AG0 SENTRON MCCB, 100A, 3P, TM240","metaDescription":"Siemens 3VA1110-4EF36-0AG0 SENTRON molded case circuit breaker, 100A rated, 3-pole, TM240 thermal-magnetic trip.
