Siemens 3VA1025-2ED32-0DA0 — SENTRON MCCB, 25 A, TM210 Release
The Siemens 3VA1025-2ED32-0DA0 is a SENTRON 3-pole molded case circuit breaker rated for 25 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated undervoltage release (UVR). Breaking capacity reaches 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — covering most low-voltage distribution and motor branch-circuit fault levels in North American and IEC installations.
Lifecycle & Sourcing — Current Production, Quoted to Order
This is not a surplus or obsolete part; it is a standard catalog line that can be specified into a BOM with confidence.
The 25 A rating holds flat from 40 °C through 50 °C, then derates to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C — so in a warm panel near the upper ambient limit, you lose about 2.5 A of headroom. It is a straight thermal bimetal plus magnetic short-circuit trip, factory-set for the 25 A frame. It is wired separately from the main power path.
Panel Fit & Dimensions
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole MCCB footprint that fits standard distribution panelboards and motor control center buckets.
