SENTRON 3VA1132-5GF46-0AA0 — 32 A 4-Pole MCCB, Line Protection
The interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V, which covers most industrial low-voltage fault levels.
At 55 °C it derates to 31 A, at 65 °C to 30 A, and at 70 °C to 30 A. The maximum power loss is 10.6 W per pole, so four poles dissipate about 42 W total; ensure the enclosure has enough ventilation or forced airflow to keep internal temperature below the 70 °C operating maximum.
The 4-pole width (101.6 mm) is standard for a 4-pole MCCB in this frame class — it occupies four 25.4 mm (1-inch) module spaces on a DIN rail or panel-mount footprint. Depth of 70 mm means it clears most standard enclosure back-panels without interfering with gland plates or busbar trunking behind it.
