SENTRON 3VM1196-4EE42-0AA0 — 16 A, 4-Pole MCCB with TM220 Release
Breaking capacity is 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at 500 V — these figures govern fault-interruption capability at the point of installation; the 415 V rating is the one most often checked for European 400 V distribution panels. Rated insulation voltage is 690 V, and the maximum rated operational voltage with DC is 500 V, so the breaker suits both AC and DC load circuits within those limits. Front protection is IP40.
Thermal Derating and Power Loss
The 16 A rating holds from 40 °C through 55 °C ambient; at 60 °C and 65 °C it derates to 15 A, and at 70 °C it remains at 15 A. No derating needed below 55 °C for most panel interiors. Maximum power loss is 10.6 W — relevant for thermal budgeting inside a sealed enclosure; ensure ventilation or a larger cabinet if multiple breakers are ganged.
