Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V. That 75.6 kA figure at 240 V means it can interrupt a fault of that magnitude without upstream fuses needing to clear — useful for high-fault panels fed close to a transformer. The 3VA1140-3EF36-0JH0 carries a higher continuous current (40 A vs the 3VA1110's rating) and different breaking capacities — verify the specific interrupting rating your coordination study requires before swapping. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without adapter plates. The 3-pole form factor matches typical 3-phase feeder or branch circuits. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.","metaTitle":"Siemens SENTRON 3VA1140-3EF36-0JH0 MCCB, 40A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1140-3EF36-0JH0 molded case circuit breaker, 40A rated at 40°C, 3-pole, 75.6kA breaking at 240V.
