The Siemens 3VA2225-5JP32-0JH0 is a SENTRON 3VA2 molded case circuit breaker rated for line protection, 3-pole, with a continuous current Iu of 250 A at 40 °C. That 250 A holds steady through 50 °C — only at 55 °C does it begin to derate to 238 A, then 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. That means you can remote-trip it or get status feedback without adding external relays. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V. On a 480 V system (common in North America) you'd interpolate between the 440 V and 500 V figures — still well above typical fault levels for a 250 A feeder.
Lifecycle and sourcing — active, no LTB watch needed
No last-time-buy or phase-out notice exists. For BOM-freeze planning, this part is a safe line item without an obsolescence clock. Rated insulation voltage 800 V and max power loss 48 W at rated current. These are standard for a 250 A MCCB in a ventilated enclosure.
That width is the standard 105 mm for a 3-pole 3VA2 frame — it fits the same DIN-rail or screw-mount footprint as other 3VA2 breakers in this current class.
