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. 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 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.
