The 3VA2325-5HL32-0DL0: Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. Thermal derating is published per degree: 250 A continuous through 50 °C, then 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C.
Release and auxiliary fit
The overcurrent release is an ETU320 — a basic electronic trip unit with fixed settings, no communication function, and no phase failure detection. That UVR is the 3VA9608-0BB25 integrated auxiliary trip. The breaker includes a mechanical trip indicator and has a latching endurance of 15 000 operations — sufficient for typical distribution switching but not for frequent motor-starting duty.
Panel fit and environment
Dimensions: 138 mm wide, 248 mm high, 110 mm deep. Maximum power loss is 40 W at rated current — factor that into your enclosure thermal calculation if you are grouping several breakers in a sealed cabinet.
