What this MCCB carries — and where it stops
The Siemens 3VA2325-6HN32-0AF0 is a SENTRON molded case circuit breaker, 3-pole, rated 250 A continuous at 40 °C and holding that same 250 A all the way up to 70 °C — no derating curve to chase across the summer shift. Breaking capacity hits 242 kA at 240 V, drops to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 7.5 kA at 690 V. That 242 kA at 240 V tells you this breaker is sized for high-fault panels — big transformer secondaries, parallel generator feeds, or industrial service entrances where the available fault current is serious. It is a line-protection design with no undervoltage release, no ground-fault monitoring, and no communication function — a straight-ahead thermal-magnetic or electronic-trip MCCB for main feeder or large branch duty. The built-in auxiliary switch and trip alarm switch (1 each, HQ type) give you a dry-contact status signal back to the PLC or annunciator.
Fit and footprint
Dimensions: 138 mm wide, 248 mm tall, 110 mm deep. That 138 mm width is the standard 3-pole MCCB footprint for this class — same mounting centres as the earlier 3VA1 series, so a panel laid out for a 3VA1110-5EF32-0AM0 should accept this 3VA2325 without drilling new holes or shifting the bus bars. Power loss is 37.5 W maximum at rated load — modest enough that standard enclosure ventilation handles it, but worth checking if you are packing multiple breakers in a sealed stainless box. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. That covers unheated warehouses and outdoor enclosures in most climates.
