At 240 V it clears 52.5 kA; at 415 V it clears 32 kA; at 440 V it clears 13.6 kA; and at 690 V it clears 7.5 kA. ## Thermal derating — the real-world current you can actually run Above that, it starts to taper: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. ## Footprint and panel integration That width is three standard 25.4 mm pole spacings, so it fits a typical 3-pole MCCB cutout in a distribution panel without surprises.","metaTitle":"Siemens 3VA1050-2ED36-0AF0 SENTRON MCCB, 50 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1050-2ED36-0AF0 molded case circuit breaker, 50 A rated, 3-pole, TM210 trip unit, breaking capacities up to 52.5 kA at 240 V.
