Siemens SENTRON 3VM1025-2ED32-0AA0 — 25 A MCCB with TM210 Release
Breaking capacity reaches 53 kA at 240 V AC, 32 kA at 415 V AC, 14 kA at 440 V AC, and 8 kA at 500 V AC — the figure drops as system voltage rises, so size the SCCR to your actual line voltage, not the highest number on the label.
Current rating holds at 25 A from 40 °C up to 50 °C ambient, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C — no reduction needed in most ventilated enclosures, but account for the drop if the breaker sits near heat sources or in a sealed cabinet. The 3-pole unit measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-inch wide footprint that drops into typical MCCB panel cutouts without reworking the bus bars.
