The Siemens SENTRON 3VA2116-6HN46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 160 A continuous, with an ETU350 electronic trip unit. Breaking capacity hits 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is the limiting case for high-voltage low-current applications. Insulation voltage is rated 800 V.
Current rating and thermal performance
Rated current holds at 160 A across the full operating temperature range from 40 °C to 70 °C — no derating needed in a warm panel. Maximum power loss is 25.5 W, which matters for enclosure heat load calculations when ganging multiple breakers.
Dimensions and panel fit
Footprint is 140 mm wide × 181 mm tall × 86 mm deep. The 140 mm width means it occupies four standard 35 mm DIN-rail module spaces (36 mm per pole plus inter-pole gaps). Bolts onto the back panel or mounts on a DIN rail adapter plate — verify the adapter for this frame size. Front IP40 protection keeps dust out of the breaker face.
