The Siemens SENTRON 3VA2325-6HL32-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed for line protection in distribution panels and motor control centers. It carries a maximum breaking capacity of 242 kA at 240 V and 187 kA at 415 V, with derating to 7.5 kA at 690 V — the SCCR headroom at typical industrial voltages (240–480 V) is substantial, so it can be applied upstream of smaller branch breakers without coordination concerns.
Current rating and thermal performance
The continuous current rating holds at 250 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That is unusual for a compact-frame MCCB; many competitors start tapering above 50 °C. The maximum power loss is 37.5 W, which matters for enclosure heat-rise calculations when grouping several breakers in a single panel.
Dimensions and panel fit
The breaker measures 110 mm deep, 138 mm wide, and 248 mm tall. The 110 mm depth is the key dimension for enclosure depth — it fits standard 200 mm deep wall-mount enclosures with room for wiring gutters. The 138 mm width (5.43 inches) means it occupies three 45 mm pole spaces on a DIN rail or panel-mount footprint.
Environmental and compliance
Operating temperature range is -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. The part is designed for line protection with no communication function, no voltage trigger, and no trip indicator. As a SENTRON series MCCB, it carries the usual Siemens compliance documentation (UL, IEC, RoHS, REACH) — confirm specific certs with the order code at quote time.
