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.
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.
