What this MCCB carries and where it fits
The Siemens SENTRON 3VA2325-5HL32-0CA0 is a 3-pole molded case circuit breaker rated for 250 A continuous current across the full 40 °C to 70 °C ambient range — no derating curve to chase. It's designed for line protection, meaning it sits at the incoming feeder or main distribution point, not downstream on a motor branch. The interrupting ratings climb to 187 kA at 240 VAC and hold at 121 kA through 440 VAC, then step down to 75.6 kA at 500 VAC and 7.5 kA at 690 VAC. That's enough SCCR headroom for most industrial service-entrance panels on 480 V or 400 V systems. The frame dimensions are 248 mm tall, 138 mm wide, and 110 mm deep — a standard SENTRON 3VA footprint that drops into existing panel layouts without re-drilling gland plates. The unit includes an undervoltage release (UVR) as the auxiliary release, so it will trip on loss of control voltage; there's no auxiliary switch or ground-fault monitoring module on this variant. Max power loss is 40 W, which matters for enclosure thermal budgeting when you're stacking several breakers in a row.
What the undervoltage release means in practice
The built-in undervoltage release (UVR) opens the breaker when control voltage drops below a threshold — common in safety circuits where a loss of pilot power must kill the main feeder. It's wired separately from the main power path, so you need a control voltage source (typically 24 VDC or 120 VAC, depending on the release coil ordered). No auxiliary switch is fitted on this variant, so if you need remote status feedback, plan for an add-on auxiliary contact block.
