Siemens 3VA1132-6EE42-0AA0 — 32 A SENTRON MCCB, 4-Pole, 220 kA IC at 240 V
Its 4-pole construction handles three-phase plus neutral, and the interrupting ratings climb to 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that govern fault-clearing capability in high-available-fault-current panelboards.
The 32 A continuous rating holds across 45 °C to 50 °C ambient without derating; above that the curve drops by 1 A per 5 °C step to 30 A at 70 °C. For a panel running at 60 °C ambient — not uncommon in a sealed enclosure near process heat — the breaker still carries 31 A, so a 32 A load requires headroom or ventilation. The adjustable li setting goes up to 320 A for the magnetic trip, letting you tune short-circuit protection to the downstream cable impedance without changing the breaker frame. Dimensions are 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-pole MCCB that fits the standard SENTRON panel footprint.
