It delivers 76 kA interrupting capacity at 240 VAC and 9 kA at 415 VAC — the 240 V figure covers the common North American panel voltage with substantial headroom above typical available fault current; the 415 V rating matters for 400 V-class European distribution where fault levels run lower. Rated current holds at 40 A from 40 °C through 50 °C, then derates to 39 A at 55–60 °C and 38 A at 65 °C, 37 A at 70 °C. That means a 40 A continuous load at 50 °C ambient is fine; above that, the thermal curve shifts and you need to either downrate the load or allow more ventilation. The TM210 release has a fixed thermal pickup at 40 A (lg) and a magnetic short-circuit pickup fixed at 400 A (li) — no field adjustment on the magnetic threshold, so coordination with downstream breakers must respect that 400 A instantaneous trip point. The 9 kA at 415 V covers European 400 V three-phase distribution. Width is 25.4 mm (1 inch) — a single pole in a standard 25 mm per-pole MCCB footprint. Depth 70 mm, height 130 mm.","metaTitle":"Siemens 3VA1140-4ED16-0AA0 SENTRON MCCB, 1-pole 40 A, 76 kA","metaDescription":"Siemens 3VA1140-4ED16-0AA0 SENTRON molded case circuit breaker, 1-pole, 40 A rated current, 76 kA at 240 VAC, TM210 release.
