At 240 V, 121 kA is generous; at 480 V, the 75.6 kA figure still covers most North American industrial services. Rated current holds flat at 160 A from 40 °C through 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. In a sealed, uncooled enclosure that sees 60 °C internal ambient, you lose 5 A — not much, but worth checking if you are running at the edge of the breaker's rating. The 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit standard MCCB panel cutouts; the 130 mm height (5.12 in) is typical for this frame size. Maximum power dissipation is 38 W — plan ventilation if multiple units are ganged in a small enclosure.","metaTitle":"Siemens 3VA1116-4EF32-0AB0 SENTRON MCCB, 160A, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1116-4EF32-0AB0 molded case circuit breaker, 3-pole, 160A rated at 40°C, 121kA breaking capacity at 240V AC.
