Interrupting capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — figures that govern selectivity coordination downstream and SCCR compliance for the panel assembly. The 130 mm height, 76.2 mm width, and 70 mm depth footprint fits standard SENTRON panel cutouts and busbar systems — a direct drop-in for existing 3VA line-protection layouts. Rated current holds at 40 A from 40 °C through 50 °C ambient, then derates to 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C — the full curve matters when the breaker shares an enclosure with heat-generating devices. Rated continuous current Iu: 40 A. Number of poles: 3. Product version: Line protection. Overcurrent release design: TM210. Latching endurance: 15,000 operations. Integrated auxiliary trip order code: 3VA9688-0BL33.","metaTitle":"Siemens 3VA1040-2ED32-0KA0 SENTRON MCCB, 40 A, 3-Pole, 52.5","metaDescription":"Siemens 3VA1040-2ED32-0KA0 SENTRON 3-pole molded case circuit breaker, 40 A rated, TM210 release, 52.5 kA at 240 V.
