The Siemens 3VA2116-0HL32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 160 A continuous current with an ETU320 electronic trip unit. That 160 A holds flat across the full ambient range from 40 °C to 70 °C — no derating curve to chase in a warm panel. The 440 kA breaking capacity at 415 V AC means it can interrupt fault currents up to that level without cascading upstream; at 690 V AC the rating drops to 187 kA, still well above typical industrial service-entrance levels.
The 3VA2116-0HL32-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA2 frame footprint. Operating temperature range is -25 °C to 70 °C; storage range -40 °C to 80 °C.
