The Siemens SENTRON 3VA2116-7HN36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current at 40–70 °C with no derating across that range — it holds 160 A all the way up to 70 °C ambient, which is unusual and simplifies panel sizing in hot environments. The interrupting ratings are high: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — so it can sit ahead of a high-fault panel without needing a current-limiting fuse upstream.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a standard 3-pole MCCB footprint for the 3VA frame size.
Maximum power loss is 25.5 W, which matters for enclosure thermal rise calculations when multiple breakers are ganged in a panel.
