Those are the numbers you hand to the arc-flash study — the 415 V figure is usually the one that governs selectivity in European 400 V distribution panels. ## Thermal derating — the real ampacity Rated 160 A from 40 °C through 50 °C, then it steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. If the panel ambient sits at 55 °C, you lose 2 A — not much, but worth confirming if you're running the bus right at the limit. The maximum power loss is 38 W, which matters for thermal rise inside a sealed enclosure. The IP40 on the front is typical for panel-mount; no IP rating on the body sides, so keep it inside the enclosure. Marked as current production — no LTB or NRND flag. That means you can spec it into a new BOM without worrying about a last-time-buy window closing mid-project.","metaTitle":"Siemens 3VA1116-4EF32-0AA0 SENTRON MCCB, 160 A, 3-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1116-4EF32-0AA0 molded case circuit breaker, 160 A at 40 °C, 3-pole, TM240 release.
