Breaking capacity reaches 121 kA at 240 V AC, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — sufficient for high-fault installations downstream of large transformers. ## Where it fits — panel and enclosure The 101.6 mm width (4 in) and 70 mm depth (2.76 in) suit standard MCCB mounting footprints in distribution boards. Front IP40 protection keeps dust and tools out of the mechanism in a closed panel. Rated current holds at 160 A from 40 °C up to 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.","metaTitle":"Siemens 3VA1116-4EF42-0AA0 SENTRON MCCB, 160A, 4-Pole, 121kA","metaDescription":"Siemens 3VA1116-4EF42-0AA0 SENTRON molded case circuit breaker, 160A rated at 40°C, 4-pole, 121 kA breaking capacity at 240 VAC.
