Above that it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Maximum power loss is 50.5 W, which matters when packing multiple breakers into a closed panel — the heat load adds up.
The basic switch assembly is order code 3VA2225-6HN32-0AA0.
This is a current-production part. No official successor has been announced.
It is rated 250 A continuous at 40-50 °C, 3-pole, with breaking capacities of 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. It includes an undervoltage release and two auxiliary switches plus a trip alarm.
