The Siemens SENTRON 3VA1025-3ED32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated 25 A at 40 °C, with a breaking capacity of 75.6 kA at 240 V AC. The thermal-magnetic trip curve is fixed for line protection — no communication module or ground-fault monitoring is fitted on this variant.
The interrupting rating drops with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Rated 25 A from 40 °C through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C. If the panel ambient sits above 50 °C, plan for the 1–2 A reduction per the thermal curve.
Integrated auxiliary devices
The auxiliary switches provide remote status indication (open/closed) for the PLC or SCADA.
Width 76.2 mm (3 in), height 130 mm (5.12 in), depth 70 mm (2.76 in). The 3-pole footprint matches the SENTRON 3VA1 family panel cutout — no adapter plate needed for a 3VA1-based switchboard.
