It's designated for line protection, meaning it's sized for feeder or main branch duty rather than motor-protection curves. The 52.5 kA interrupting rating at 240 V drops to 32 kA at 415 V and 13.6 kA at 440 V, so the available fault current at the installation point has to be checked against the voltage-specific column, not the highest number. Rated current holds flat at 32 A from 40 °C up to 50 °C, then derates gently to 30 A at 70 °C — that's a tight thermal window, so in a hot enclosure you lose only 2 A.
Breaking capacity across voltages — where it fits
This MCCB's interrupting capacity is specified per voltage level, not as a single Icu number. At 240 V it handles 52.5 kA — typical for North American 240/120 V split-phase or 240 V three-phase panels. At 415 V (common in IEC 50 Hz grids) it's 32 kA, and at 440 V it's 13.6 kA. Selectivity studies should use the voltage-specific column for the point of installation.
The 3VA1032-2ED42-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole footprint that fits standard SENTRON mounting plates and DIN-rail adapters. The 101.6 mm width (4 inches) matches the 4-pole form factor of the 3VA1 family; panel cutouts and busbar spacing designed for 3-pole units will need a wider slot.
