SENTRON 3VA2325-5HN32-0KH0 — 250 A MCCB with ETU350
The interrupting ratings are 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 — numbers that define the available fault current it can safely clear at each voltage level without upstream coordination failure. The 250 A rating holds flat from 40 °C through 50 °C; above that it derates to 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C. The ETU350 release is field-configurable for long-time, short-time, instantaneous, and ground-fault pickup — though this unit ships without ground-fault monitoring (the 'Without' flag on that option).
The shunt trip (STL) allows remote tripping from an E-stop or PLC output. The auxiliary switch block reports open/closed status and the alarm switch signals a trip event — useful for a BMS or SCADA input.
