You set it, you lock it, you move on. Breaking capacity is the headline number here: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. At 690 V it still clears 11.9 kA, which covers most industrial motor loads. ## Sizing and thermal performance At 55 °C it drops to 122 A, at 60 °C to 120 A, at 65 °C to 117 A, and at 70 °C to 114 A. If your enclosure runs hot, you lose about 1 A per degree above 50 °C. That's predictable and easy to factor into the wire and bus sizing. Maximum power loss is 28.1 W. That's the heat the breaker dumps into the enclosure at full rated current. For a multi-breaker panel, that heat adds up — account for it in the ventilation or cooling calculation. Dimensions: 130 mm tall, 101.6 mm wide, 70 mm deep. The 4-pole width is about 4 inches — standard for a 4-pole MCCB in this class. Mounting is via the rear panel or a DIN rail adapter (not included). The IP40 front face is fine for a closed panel; if the door is open for commissioning, treat it as unprotected. A motor drive option is available as a product extension. The manual for DC applications is available separately under Service & Support.","metaTitle":"Siemens 3VA1112-3ED46-0AA0 SENTRON MCCB, 125A, 4-Pole, TM210","metaDescription":"Siemens 3VA1112-3ED46-0AA0 SENTRON molded case circuit breaker, 125A at 40°C, 4-pole, TM210 release, breaking capacity 75.6 kA at 240 V.
