The Siemens 3VA2116-0HN36-0AA0 is a 3-pole IEC molded case circuit breaker from the 3VA2 series, rated at 160 A continuous with an Icu of 200 kA at 415 V AC. That 200 kA interrupting rating puts it in breaking capacity class E — high enough for most transformer-fed or generator-fed main feeders where fault currents can exceed 100 kA. For a site electrical engineer building a selective coordination study, this breaker's ETU350 electronic trip unit (LSI) gives you adjustable long-time (Ir = 63…160 A), short-time (Isd = 1.5…10xIr), and instantaneous (Ii = 12xIn) protection, so you can shape the trip curve to stay selective with downstream 3VA1 or 3VA2 feeders.
Packaged as a single piece (200 x 134 x 145 mm). The 3VA2 frame 160 uses a standard screw-mount or plug-in base for panel or enclosure installation. Terminal connections are included. No DIN-rail clip — this is a bolted-frame MCCB, so factor in the mounting footprint and bus-bar connections when laying out the switchboard.
