The 25.4 mm width (1 inch) matches standard DIN-rail or panel-mount footprints — one module wide, so it slots into existing SENTRON sub-distribution boards without re-spacing. Rated current holds at 40 A through 50 °C, then derates to 39 A at 55–60 °C, and 38 A at 65 °C, 37 A at 70 °C — the TM210 trip curve stays within spec across the operating range. Breaking capacity is 52.5 kA at 240 V AC and 7.5 kA at 415 V AC; the 415 V figure is the one to check if the panel feeds a 400 V line. Insulation voltage is rated 500 V, operating voltage 415 V AC / 125 V DC. Depth is 70 mm (2.76 in), height 130 mm (5.12 in) — fits standard SENTRON enclosures and most 200 mm-deep distribution boards. Ground-fault monitoring is not built in; if that is needed, add an external module or specify a different variant.","metaTitle":"Siemens 3VA1140-3ED12-0AA0 SENTRON MCCB, 40A 1-Pole, 52.5kA","metaDescription":"Siemens SENTRON 3VA1140-3ED12-0AA0 molded case circuit breaker, 40A rated, 1-pole, 52.5kA breaking at 240V AC.

The 5SJ3140-7 is a miniature circuit breaker (MCB), not a direct MCCB replacement; it occupies the same 1-module width but has a lower interrupting rating."},{"question":"What compliance documentation does Siemens provide for 3VA1140-3ED12-0AA0?","answer":"Standard SENTRON MCCBs carry CE marking, UL/CSA recognition, and RoHS/REACH declarations.
