Siemens SENTRON 3VA2325-6HL32-0BA0 — 250 A MCCB with ETU320 Trip Unit
The Siemens SENTRON 3VA2325-6HL32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 250 A at 40 °C and holding that rating through 50 °C before a gentle derating curve begins — 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C. That thermal profile means it can sit in a warm panel without losing capacity until ambient pushes past 50 °C, which covers most standard industrial enclosures. Breaking capacity is the headline number that decides fault-clearing fit: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. Maximum power loss is 40 W — a figure to check against enclosure thermal dissipation when the breaker is fully loaded.
Lifecycle and Sourcing — Active Production, Quoted to Order
The ETU320 release and undervoltage release are standard fit on this variant, so no separate ordering of the trip unit is needed.
Panel Integration — Dimensions and Mounting
Mounting dimensions: 248 mm height, 138 mm width, 110 mm depth. The 138 mm width for a 3-pole frame is standard for SENTRON 3VA2 breakers in this rating class, so it fits existing cutouts and busbar spacing in a distribution board or motor control center. Depth of 110 mm is shallow enough for most 400 mm deep enclosures with clearance for rear cable connections.
