The thermal derating curve is flat from 40 °C to 50 °C at 250 A, then steps down: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. ## Trip unit and auxiliary contacts The ETU320 is an electronic overcurrent release with a trip indicator. It does not include ground-fault monitoring or a communication function — this is a straightforward line-protection breaker, not a power-monitoring device. The basic switch assembly is order code 3VA2225-5HL42-0AA0. ## Physical fit","metaTitle":"Siemens 3VA2225-5HL42-0DH0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2225-5HL42-0DH0 SENTRON molded case circuit breaker, 250 A rated, 4-pole, ETU320 trip unit, 187 kA at 240 V.
