The Siemens 3VA2216-8HL32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current, with a maximum breaking capacity of 440 kA at 240 V AC. That 440 kA figure is the headline — it means this breaker can safely interrupt a fault current up to 440,000 amps at 240 V without welding its contacts or venting plasma into the panel. At 415 V and 440 V it still holds 330 kA, and at 690 V it's rated 52.5 kA, so it covers high-fault installations from 240 V through 690 V without needing a current-limiting fuse upstream.
Trip unit and protection
It carries an ETU320 electronic trip unit, which is the adjustable thermal-magnetic replacement in the 3VA line. The trip unit is designed for line protection — no ground-fault monitoring, no undervoltage release, no communication module. The adjustable current range runs from 240 A minimum to 1,920 A maximum, so you set the magnetic pickup to match your load's inrush without nuisance tripping. Power loss is 19.7 W max, which matters for thermal coordination inside a sealed enclosure.
Physical fit and environment
Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — a 3-pole frame that drops into a standard SENTRON mounting base. The front face carries IP40 protection, so it's fine inside a panel but not for washdown zones. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. The 160 A rating holds flat across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C, which is unusual for an MCCB this size.
