The Siemens SENTRON 3VA2225-0HN32-0AF0 is a 3-pole molded case circuit breaker rated 250 A at 40 °C, fitted with an ETU350 electronic trip unit.
At 40 °C the breaker is good for 250 A continuous. That holds flat through 50 °C (250 A), then drops to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. IP40 on the front keeps dust out of the trip-unit compartment in a clean enclosure.
440 kA at 415 V AC, and 187 kA at 690 V AC.
