What this MCCB carries
The Siemens 3VA2325-6KP32-0AA0 is a SENTRON 3VA2-series molded case circuit breaker rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It is a 3-pole unit designed for line protection, fitted with the ETU850 electronic trip unit. Breaking capacity reaches 242 kA at 240 V and 187 kA at 415 V and 440 V, stepping down to 121 kA at 500 V and 7.5 kA at 690 V. That 242 kA at 240 V tells you this breaker handles high-fault utility or transformer-fed downstream panels without cascading upstream. The ETU850 release supports communication and additional measurement functions, so it feeds power-quality data back to a BMS or PLC — not just a dumb overcurrent trip.
What the ratings mean for panel fit
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint for 250 A frame size. Front IP40 protection means it is suited for enclosed panel mounting where incidental tool or finger contact is the only exposure; no washdown rating on the front face. The adjustable overcurrent release range spans 375 A to 3 000 A — that is the magnetic/instantaneous pickup window, not the continuous rating. The continuous rating is fixed at 250 A; the ETU850 lets you dial in the short-circuit and short-time pickup within that band for selective coordination downstream. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Maximum power loss is 37.5 W — relevant for thermal budgeting inside a sealed enclosure with multiple breakers in a row.
Compliance and documentation
As a SENTRON 3VA2 product, this MCCB is designed and tested to IEC 60947-2 and carries the associated CE marking for European markets. RoHS and REACH compliance documentation is standard from Siemens for the 3VA series. No UL or CSA listing is confirmed in the available data — verify with the full datasheet if UL 489 listing is required for your jurisdiction.
