The IP40 front protection means it's suited for installation inside a dead-front enclosure where the operator side is protected from tool or finger contact. Above that, the breaker derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. For a panel that runs warm — say a packed MCC lineup at 55 °C — the effective continuous current drops to 153.6 A, so the connected load must stay under that figure to avoid nuisance tripping. The breaker measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON panelboards and switchboard cubicles without adapter plates. The shunt trip (STL) and auxiliary switches are factory-integrated; no field-add-on kit required.","metaTitle":"Siemens 3VA1116-3EF32-0KC0 SENTRON MCCB, 160 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1116-3EF32-0KC0 molded case circuit breaker, 160 A rated, 3-pole, 75.6 kA at 240 V.
