It's a current-production part, so this is what you'd spec into a new BOM or use as a direct replacement for an existing 3VA2 frame in the field.
Breaking capacity and what it means for your panel
The interrupting ratings here are substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V.
Rated 160 A continuous up to 50 °C ambient, then it derates: 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. The 25.5 W maximum power loss matters for enclosure thermal calculations too.
Trip unit and auxiliary contacts
The ETU320 is an electronic trip unit with LI (long-time and instantaneous) protection curves — no ground-fault or voltage-trip function on this variant. No undervoltage release, no communication module, no phase-failure detection; this is a straightforward thermal-magnetic replacement with electronic precision.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint for a 160 A frame.
