The Siemens 3VA2116-8HN42-0AA0 is a SENTRON molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.
This breaker clears 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V.
Dimensions are 86 mm deep, 140 mm wide, and 181 mm tall. That's a standard 4-pole MCCB footprint for a 160 A frame — fits existing SENTRON 3VA panel cutouts and busbar systems. Front protection is IP40, so it's suited for enclosed distribution boards where tools or fingers won't contact live parts through the front cover.
Trip unit and protection characteristics
Power loss is 19.7 W maximum at rated current, which matters for thermal management inside a sealed enclosure. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C.
