Breaking capacity is the key fit question for a main breaker: this one delivers 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. At 690 V the 17 kA rating is lower, but still adequate for most 690 V motor control center applications where the transformer impedance limits fault current. Thermal derating is published: 250 A continuous from 40 °C 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. Maximum power loss is 37.5 W, which feeds into the enclosure heat budget.
The 3VA2325-5HN32-0JA0 measures 138 mm wide, 248 mm tall, and 110 mm deep.
What it does not include
This version ships without auxiliary contacts, without a trip indicator, without an undervoltage release, without ground-fault monitoring, without communication, and without phase-failure detection. If your application requires any of those — say, a remote trip signal to a PLC or ground-fault protection on a solidly-grounded system — you need a different 3VA2 variant or an accessory kit. The shunt trip (STL) is the only auxiliary release fitted.
