It interrupts 53 kA at 240 V AC and 8 kA at 415 V AC — the 415 V figure governs most European industrial panel applications, while the 240 V rating covers North American 120/240 V split-phase or 277/480 V wye-derived single-pole branch circuits. Thermal derating is flat from 40 °C to 50 °C at 40 A, then steps down to 39 A at 55 °C, 38 A at 65 °C, and 37 A at 70 °C. The IP40 front protection keeps out tools and finger contact during panel work. ## Coordination and selectivity note That simplifies ordering but locks the protection curve; if your design requires adjustable long-time pickup or ground-fault, step up to the 3VA series with electronic trip units. For a direct functional cross-reference within the Siemens MCCB family, the 3VA1020-3ED36-0AA0 is a 1-pole, 40 A, 25 kA at 415 V AC unit with an electronic trip. The 3VM holds a higher interrupting rating (53 kA at 240 V) and uses a simpler thermal-magnetic release; the 3VA offers adjustable trip settings and a higher 415 V breaking capacity. Verify footprint compatibility — the 3VA series shares the same 25.4 mm width and DIN-rail mount, but the depth and terminal layout differ slightly.","metaTitle":"Siemens 3VM1140-3ED16-0AA2 SENTRON MCCB, 1P, 40A, 53kA/240V","metaDescription":"Siemens SENTRON 3VM1140-3ED16-0AA2 molded case circuit breaker, 1-pole, 40 A rated at 40 °C, 53 kA at 240 V AC, 8 kA at 415 V AC.
