The Siemens SENTRON 3VA1116-4EE32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line-protection duty, carrying a continuous current of 160 A at 40 °C and delivering a short-circuit breaking capacity of 121 kA at 240 V AC. That interrupting rating drops to 75.6 kA at 415 V and 52.5 kA at 440 V, still well above typical industrial service-entrance or distribution-panel fault levels.
Rated current holds at 160 A from 40 °C through 50 °C ambient, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 38 W. In a sealed or high-fill-factor panel, that derating curve matters — a breaker mounted next to other heat sources may need to be loaded below its nameplate to stay within the thermal trip curve.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard Siemens SENTRON mounting patterns.
