Siemens SENTRON 3VA2225-5HN42-0JA0 — 250 A MCCB with Shunt Trip
The Siemens SENTRON 3VA2225-5HN42-0JA0 is a 4-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed for line protection in industrial distribution panels. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 500 V — at 690 V it still clears 4.5 kA, so the part carries headroom across common low-voltage system levels. The breaker includes a factory-installed shunt trip release (STL) for remote tripping via a control voltage — useful for emergency-stop or supervisory shutdown circuits where you need to open the main breaker without a manual handle pull. Thermal derating is published across the full 40 °C to 70 °C operating band: the breaker holds 250 A up to 50 °C, then steps down to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. If your panel ambient runs above 50 °C, factor the derated current into your load schedule.
Lifecycle & Sourcing Reality
For a BOM freeze or a line-down replacement, this part is sourced to order against an RFQ. Availability and current pricing are confirmed at quote time through our independent distribution network — think landed, not list. The paperwork has to be clean: Siemens typically provides CE, UL, and IEC declarations with the shipment; RoHS and REACH compliance documentation is available on request.
Panel Fit & Integration
Physical footprint: 140 mm wide, 181 mm tall, 86 mm deep — a 4-pole MCCB that fits standard Siemens SENTRON mounting plates and busbar systems. The depth is 86 mm. Maximum power loss is 48 W at rated current — account for that heat in your enclosure thermal calculation, especially if multiple breakers are ganged in a single panel. Operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. The storage limit governs handling and warehousing, not running conditions.
