The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The overcurrent release is an ETU350 — that's a basic electronic trip unit with LSI curves (long-time, short-time, instantaneous). It's a workhorse MCCB for standard distribution and motor feeder protection where you don't need the bells of a 3VA2 with a 3VA9 communication module. Footprint is 138 mm wide, 248 mm tall, 110 mm deep. That's a standard 3VA2 frame size — it bolts into the same mounting pattern as other 250 A SENTRON MCCBs. No DIN-rail mount on this class; it's fixed by four screws to a backplate or busbar system. Wireway planning: at 250 A you're looking at parallel runs of 70 mm² or 95 mm² copper, so leave at least 150 mm clearance below the breaker for cable sweep. In practice, for selectivity coordination downstream of a larger feeder, you'd look at the short-time withstand and the ETU350's adjustable I²t curves. The 121 kA at 415 V is the figure most European 400 V panels care about; the 17 kA at 690 V is the ceiling for 690 V industrial networks. ## Endurance and thermal budget Mechanical endurance is 15,000 operations — that's typical for a 250 A frame MCCB used in distribution, not for frequent switching duty. If you're cycling this breaker daily as a disconnect, you'll wear it out faster than the 15k cycles. The maximum power loss is 40 W at rated current; that's heat that has to be dissipated inside the enclosure. In a sealed panel with multiple breakers, factor that into the thermal calculation — 40 W per pole is 120 W total for this 3-pole unit at full load.","metaTitle":"Siemens 3VA2325-5HN32-0DA0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2325-5HN32-0DA0 SENTRON MCCB, 250 A rated at 40 °C, 3-pole, ETU350 release, 187 kA at 240 V.
