At 415 V the rating drops to 121 kA, and at 690 V to 17 kA, which still covers most motor branch circuits on 690 V systems. The thermal derating curve is flat from 40 °C to 50 °C (125 A), then steps down to 114 A at 70 °C — useful to know if this breaker lives in a non-ventilated enclosure near other heat sources. ## Panel fit and auxiliary complement The 3VA1112-5ED32-0DH0 measures 130 mm high × 76.2 mm wide × 70 mm deep — a 3-module-wide footprint that fits the standard SENTRON mounting pattern on a DIN rail or screw-fixed backplate. The trip indicator on the front gives a visible flag when the breaker has opened on a fault, which speeds panel walk-downs.","metaTitle":"Siemens 3VA1112-5ED32-0DH0 SENTRON MCCB, 125 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1112-5ED32-0DH0 molded case circuit breaker, 125 A, 3-pole, 187 kA breaking capacity at 240 VAC.
