At 55 °C it drops to 241 A, at 60 °C to 232 A, and at 70 °C to 213 A. The ETU320 electronic trip unit gives adjustable long-time, short-time, and instantaneous protection; the undervoltage release (UVR) lets a safety circuit or E-stop drop the breaker without a manual trip.
The 3-pole design with line-side and load-side terminals accepts copper or aluminum conductors up to the rated cross-section. No auxiliary contacts or communication module are fitted on this variant, but the slot accepts the 3VA9608-0BB25 auxiliary trip accessory if needed later.
