The 4-pole configuration covers three-phase plus neutral, with the N-conductor protection adjustable from OFF to 20–160% of the phase rating. That's handy for panels where the neutral load isn't symmetrical — common in VFD-fed lines or lighting distribution. This breaker's interrupting ratings span the voltage range you'll see in most industrial switchgear: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. For typical 480 V North American panels, the 220 kA at 500 V rating gives comfortable headroom even on high-capacity transformers. ## Trip unit and adjustability The ETU860 electronic trip unit is the brains here — it's adjustable for I-trip, giving you selectivity tuning without swapping trip packs. The ground-fault monitoring uses summation current formation on L+N, which is the standard approach for 4-pole breakers protecting solidly-grounded systems. Communication function is built in, so this breaker can talk to a BMS or PLC for power monitoring and remote trip indication — no separate module needed. Dimensions: 248 mm tall, 184 mm wide, 110 mm deep (–). That's a standard 4-pole MCCB footprint — it'll drop into most SENTRON or competitor panel-mounting bases without re-drilling. Power loss maxes at 37.5 W — negligible for cabinet heat load.","metaTitle":"Siemens 3VA2325-8KQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 440","metaDescription":"Siemens SENTRON 3VA2325-8KQ42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU860 electronic trip, 440 kA at 240 V.
