160 A MCCB with ETU320 — what the ratings mean for your panel
The Siemens SENTRON 3VA2216-6HL42-0AA0 is a 4-pole molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C — no derating needed across that band, which simplifies panel layout in warm enclosures. Its ETU320 electronic trip unit (line protection design) provides adjustable overload and short-circuit protection; the breaker carries a maximum breaking capacity of 242 kA at 240 V and 4.5 kA at 690 V. Rated insulation voltage is 800 V, and the front face carries IP40 protection — fine for a clean indoor panel, but not for washdown zones.
Physical fit — what ships in the carton
Dimensions are 181 mm high × 140 mm wide × 86 mm deep — a standard MCCB footprint for 160 A frame size, so it drops into existing 3VA panel cutouts without rework. No undervoltage release, no voltage trip, no communication module, no ground-fault monitoring — this is a straight line-protection breaker with the ETU320 as the only release. Maximum power loss is 19.7 W — factor that into your enclosure thermal budget if you're stacking several breakers in a sealed cabinet.
