What this MCCB brings to a panel
It carries a breaking capacity of 75.6 kA at 240 V, stepping down to 52.5 kA at 415 V and 32 kA at 440 V, which gives you selectivity headroom against downstream branch devices in a 400 V industrial network.
Thermal derating and power dissipation
At 60 °C and 65 °C it derates to 15 A, and at 70 °C it stays at 15 A — so in a hot panel near the top of a cabinet, you lose 1 A of continuous capacity.
The 3VA1196-3GD42-0AA0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall. The 4-pole configuration covers three-phase-plus-neutral or three-phase with a switched neutral, depending on your system design.
