At 55 °C it drops to 241 A, at 60 °C to 232 A, and at 70 °C to 213 A. The maximum power loss of 48 W at rated current should be factored into the enclosure thermal budget.
Auxiliary contacts and wiring
It ships with two auxiliary switches (HP type) built in, so you get status feedback without adding a separate accessory block. The ETU320 is a basic electronic trip with no communication or phase-failure detection; if you need those, step up to the ETU6xx series.
Environmental limits
The storage limit matters for warehousing — keep it above -40 °C and below 80 °C to avoid seal or plastic degradation before installation.
