What this MCCB carries — and where it fits
The Siemens SENTRON 3VA2216-7HN32-0AA0 is a 3-pole molded case circuit breaker rated 160 A continuous, with an ETU350 electronic trip unit. Its interrupting capacity hits 330 kA at 240 V AC, dropping to 242 kA at 415/440 V, 187 kA at 500 V, and 4.5 kA at 690 V — the high-end short-circuit rating at 240 V tells you this breaker is designed for strong-fault panels, likely on the secondary side of a large transformer or in a high-capacity distribution board where fault current runs deep. The 160 A rating holds flat from 40 °C through 70 °C ambient — no derating curve to chase in a warm enclosure, which simplifies panel layout for a machine-tool or process-line cabinet where internal temperature climbs. Designed for line protection (feeder duty), not motor protection — the ETU350 is a basic electronic trip with adjustable overload and short-circuit settings, but no ground-fault monitoring or communication function built in. The front face carries IP40 protection, adequate for a clean indoor panel but not washdown.
Panel fit and dimensions
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. The 105 mm width is the standard 4-module footprint for a 3-pole SENTRON 3VA frame — drops into the same DIN-rail or screw-mount panel cutout as other 3VA breakers of this frame size. No rewiring needed if replacing a 3VA2110-8HN32-0AA0 or similar sibling; the lug centres and bus-bar pitch are identical.
Compliance documentation
As a current-production Siemens SENTRON MCCB, the 3VA2216-7HN32-0AA0 ships with the standard compliance pack: CE marking for the European market, UL/CSA listing for North American panels, and RoHS/REACH material declarations. The specific certificate numbers and declaration of conformity are available with the shipment documentation.
