What this MCCB delivers on the panel
The Siemens 3VA1032-2ED42-0AA0 is a 4-pole SENTRON molded case circuit breaker rated 32 A continuous (Iu) with a TM210 thermal-magnetic release — fixed thermal and magnetic trip settings, no adjustment needed. 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. At 690 V it still holds 7.5 kA, which covers most 690 V industrial distributions. 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. The TM210 release is the standard thermal-magnetic type for distribution panels; no electronic trip unit, no communication module, no undervoltage release on this variant. Power loss at full load is 10.6 W, which matters for enclosure heat budget if you're stacking several breakers in a sealed cabinet.
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. The 7.5 kA rating at 500 V and 690 V is the same, which suggests the arc chamber is optimized for the lower-voltage range. Rated insulation voltage is 800 V, so the breaker is physically rated for 690 V systems but the short-circuit performance at that voltage is modest. Selectivity studies should use the voltage-specific column for the point of installation.
Physical fit and mounting
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. Front protection is IP40, so it's fine in a clean indoor panel but not for washdown zones. 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. No trip indicator on the front, so fault indication relies on the breaker handle position or an external auxiliary contact (not included on this variant).
