Its breaking capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that tell you this breaker handles high-fault-current industrial feeders, not just branch circuits. The TM240 release means the thermal element is fixed at 160 A (no adjustment band), while the magnetic pickup is set at 240 A; you're not tweaking this one in the field, so the BOM spec needs to be right before ordering. Rated insulation voltage is 800 V, and the breaker carries an IP40 protection class on the front — sealed against tools and wires over 1 mm, but not washdown. The 70 mm depth and 76.2 mm width fit standard SENTRON panel footprints; the auxiliary contact version includes one auxiliary switch plus one trip alarm switch (HQ type), so you get both a position signal and a separate fault signal without adding external relays. The 160 A rating holds flat from 40 °C through 50 °C ambient. Above that, it 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. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. ## Mechanical Endurance and Auxiliary Contacts","metaTitle":"Siemens 3VA1116-4EF32-0AF0 SENTRON MCCB, 160 A, 3-Pole","metaDescription":"Siemens 3VA1116-4EF32-0AF0 SENTRON molded case circuit breaker, 160 A rated continuous current, 3-pole, TM240 release.
