Product details
Siemens 3VM1025-3ED36-0AA2 — 25 A MCCB, 76 kA at 240 V
Its interrupting capacity hits 76 kA at 240 V AC, dropping to 53 kA at 415 V and 32 kA at 440 V — numbers that govern fault-clearing in a 400 V distribution panel. The TM210 thermal-magnetic release handles overload and short-circuit trip curves without an undervoltage or shunt trip accessory built in. Power dissipation maxes at 9 W, which matters for thermal budgeting in a densely packed enclosure.
The 76 kA at 240 V is the headline number, but the real-world figure for a 400 V industrial panel is 53 kA at 415 V. At 500 V the interrupting capacity drops to 8 kA, so this part is unsuitable for 480 V or 500 V distribution unless the fault current is known to be below that threshold. The thermal derating curve is flat from 40 °C to 50 °C at 25 A, then eases to 24 A at 55–60 °C and 23 A at 65–70 °C.
The 3VM1025-3ED36-0AA2 occupies a 76.2 mm wide by 130 mm tall footprint, with a depth of 70 mm behind the panel. That is a standard 3-pole MCCB envelope — it fits a 3-inch wide DIN-rail or screw-mount slot. The IP40 front face means it is suited for a dead-front enclosure; no gland-plate sealing is required for the breaker itself.
