Temperature derating — don't oversize the 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. If your panel runs hot — near a furnace line, in a sun-exposed cabinet, or packed with other heat sources — you must apply this derating or the breaker will nuisance-trip on a load it should carry.
Auxiliary contacts and trip options
Communication and measurement functions
The breaker supports communication (fieldbus or serial interface to a higher-level control system) and other measurement functions — meaning it can report current, power, energy, and trip event data over the network. That makes it suitable for energy monitoring and predictive maintenance setups without needing a separate power meter on the feeder.
