At 415 V it still clears 121 kA, and at 440 V it holds 75.6 kA, so it fits distribution panels where fault current runs high. The 3VA1150-5EF32-0DH0 mounts on a DIN rail or panel-mount base — the 76.2 mm width (3 in) and 130 mm height (5.12 in) fit standard SENTRON enclosure cutouts. Depth is 70 mm (2.76 in), so it clears shallow backboxes. The undervoltage release (UVR) is factory-fitted; no field kit needed. At 55 °C it derates to 49 A, at 60 °C to 48 A, at 65 °C to 46 A, and at 70 °C to 45 A.","metaTitle":"Siemens 3VA1150-5EF32-0DH0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1150-5EF32-0DH0 molded case circuit breaker, 50 A, 3-pole, interrupting rating 187 kA at 240 V.
