What this MCCB delivers for your panel
The Siemens 3VA2325-6HL32-0DL0 is a SENTRON molded case circuit breaker sized for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 3-pole design handles line protection duty, with a breaking capacity of 242 kA at 240 V and 187 kA at 415 V, which gives substantial SCCR headroom for most industrial distribution panels. The unit includes an undervoltage release (UVR) and a full auxiliary switch complement: two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ configuration).
Breaking capacity across voltage — what it means for coordination
At 240 V the breaker clears 242 kA; at 415 V and 440 V it holds at 187 kA; at 500 V it still manages 121 kA. Only at 690 V does the rating drop to 7.5 kA — a steep roll-off that matters if your panel feeds a 690 V bus. For typical 400 V class distribution the 187 kA figure is well above what most upstream transformers can deliver, so selectivity with downstream devices is straightforward.
Panel fit and dimensions
The breaker measures 138 mm wide, 248 mm high, and 110 mm deep. Those dimensions are standard for a 250 A frame SENTRON 3VA2 MCCB — it mounts on a DIN rail or directly to a backplate with the supplied hardware. The depth of 110 mm means it clears most standard enclosure gland plates without interference.
