Siemens 3VA1132-4ED22-0AA0 — 2-Pole MCCB for Line Protection
It carries a 32 A rated current at 40 °C through 50 °C, with a slight derating to 30 A at 70 °C — the thermal curve is flat across the typical panel ambient range, so no mid-range adjustment is needed. Breaking capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V AC, giving solid headroom for high-fault installations.
Two-pole configuration (2P) suits single-phase line feeds or two-wire branch circuits. Maximum power loss is 7.06 W — negligible for panel thermal budgeting, but worth summing if the enclosure holds dozens of these in a sealed cabinet.
Dimensions are 130 mm height, 50.8 mm width, 70 mm depth — a standard 2-pole MCCB footprint that fits SENTRON 3VA1 distribution blocks and most DIN-rail or screw-mount panel layouts. Width at exactly 2 inches matches the common 50.8 mm busbar pitch.
