The 40 A rating holds across 40 °C to 50 °C ambient (no derating needed up to 50 °C), then drops to 39 A at 55 °C and 37 A at 70 °C. The 121 kA at 240 V AC is the interrupting rating; at 415 V AC it's still 75.6 kA, which covers most transformer-fed secondary faults. The front panel carries IP40 protection — fine for a dry indoor panel, not for washdown areas. ## Panel integration The breaker measures 70 mm deep, 50.8 mm wide, and 130 mm high — a 2-pole footprint that fits standard DIN-rail or panel-mount enclosures. The TM210 release is fixed, so coordination studies should account for its thermal-magnetic curve.","metaTitle":"Siemens 3VA1140-4ED22-0AA0 SENTRON MCCB, 40A, 2-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1140-4ED22-0AA0 molded case circuit breaker, 40A rated at 40°C, 2-pole, 121kA breaking capacity at 240V AC.
