At 415 V and 440 V it still holds 121 kA, and at 500 V it's rated 75.6 kA, so it handles industrial supply voltages without cascading. The 250 A frame holds that rating flat from 40 °C to 50 °C; above that it derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C — important if the breaker sits in a warm enclosure or next to other heat sources. The basic switch variant is 3VA2225-5JP32-0AA0. No ground-fault monitoring is built in. Maximum power loss is 50.5 W, which factors into enclosure thermal calculations.
The 3-pole form factor with line-side and load-side lugs accepts copper or aluminum conductors sized for 250 A. The communication function allows integration with a higher-level monitoring system, useful for energy management or remote trip indication.
