What this MCCB delivers for a critical-feeder panel
The Siemens 3VA2225-5JP32-0CL0 is a 3-pole SENTRON molded case circuit breaker rated for a continuous current of 250 A, configured for line protection with an ETU550 electronic trip unit. It carries a breaking capacity of 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 — so the same frame can handle high-fault utility feeds (240 V) down to a 690 V motor branch without swapping the breaker. The thermal derating curve is published: full 250 A up to 50 °C, then linearly down to 200 A at 70 °C. For a data-center or industrial panel where ambient inside the enclosure can hit 50–55 °C, you size the load at 238 A (55 °C) or 225 A (60 °C) — the breaker itself doesn't lose headroom until you cross 50 °C.
Panel-fit and auxiliary integration
Footprint: 105 mm wide, 181 mm high, 86 mm deep — standard 3-pole MCCB envelope for a 250 A frame. It ships with an undervoltage release (UVR) and a complement of auxiliary contacts: 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch (HQ variant). The basic switch is order code 3VA2225-5JP32-0AA0; the integrated auxiliary trip is 3VA9608-0BB24. If you are replacing an existing 3VA2225-5JQ32-0AK0 in a panel, the physical mounting and bus-bar centers are identical — same 105 mm width, same depth — so no rewiring or drilling is needed. The difference is the trip unit and auxiliary contact configuration; verify the control wiring matches the UVR and alarm contacts.
Approvals and compliance documentation
The SENTRON 3VA series carries UL, CSA, and IEC certifications as standard for the platform. RoHS and REACH declarations are published by Siemens for the 3VA family; the specific order code is covered under those blanket compliance documents. No separate per-unit paperwork is required for EU or North American installations.
