At 55 °C it drops to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A. If your enclosure ambient runs 60 °C, you lose 5 A from the nameplate; plan your load at 155 A max continuous. ## Environmental and operating limits No trip indicator, no voltage trigger, no other measurement function.","metaTitle":"Siemens 3VA1116-4EF32-0CA0 SENTRON MCCB, 160A, 3-Pole, 121kA","metaDescription":"Siemens 3VA1116-4EF32-0CA0 SENTRON molded case circuit breaker, 160A rated at 40°C, 3-pole, 121kA breaking at 240V.
