The headline number that decides whether it clears a fault without upstream damage is the interrupting capacity: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The ETU560 electronic trip unit handles the overcurrent protection curve. It is a line-protection version — no voltage trigger, no phase failure detection, no ground-fault measurement beyond summation-current formation on the L conductor. Communication function is present, which means the trip unit can report status and events over a bus, but the exact protocol is not specified in this listing.
Thermal derating — the real continuous current in a warm panel
At 45 °C it derates to 600 A, at 50 °C to 570 A, at 55 °C to 540 A, at 60 °C to 510 A, at 65 °C to 480 A, and at 70 °C to 450 A. Power loss at full rated current is 164.5 W maximum, which contributes to the internal temperature rise and must be factored into the enclosure's thermal budget.
