The 125 A rating holds up to 50 °C ambient; above that it derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. The overcurrent release is a TM210 — thermal-magnetic, fixed at 10× Iu (1250 A instantaneous pickup). That's a standard motor or distribution curve; it coordinates well downstream of a larger MCCB or upstream of contactors. The N-conductor protection is 100%, so the neutral pole is fully rated, not just switched. ## Panel integration That 101.6 mm width (4 inches) is standard for a 4-pole MCCB in this frame size — it occupies four 25 mm pole spaces on a DIN rail or panel-mount footprint.","metaTitle":"Siemens 3VA1112-6GD42-0AA0 SENTRON MCCB, 125 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1112-6GD42-0AA0 4-pole MCCB, line protection, 125 A rated, 220 kA at 240 V, TM210 release.
