Siemens SENTRON 3VA2225-8JP32-0AA0 — 250 A Line-Protection MCCB with ETU550 Trip Unit
Its interrupting capacity reaches 440 kA at 240 VAC, 330 kA at 415 VAC and 440 VAC, 220 kA at 500 VAC, and 52.5 kA at 690 VAC — covering high-fault utility feeds and large motor branch circuits where the available short-circuit current is substantial. This makes the breaker suitable for integration into power-monitoring and energy-management systems without an external add-on module. The IP40 rating on the front means the breaker face is protected against solid objects over 1 mm but not sealed against moisture; panel builders should plan for an IP54 or higher enclosure if washdown or outdoor installation is required.
The 3VA2225-8JP32-0AA0 is rated for 250 A continuous up to 50 °C ambient. Above that, derating applies: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. For a panel designer, this means the breaker can be installed in a non-air-conditioned electrical room or near a heat source, as long as the continuous load is adjusted per the ambient curve.
