Its 80 A rated current at 40 °C holds steady through 50 °C before derating to 74 A at 70 °C — the thermal curve matters if your panel runs hot. Four poles suit three-phase plus neutral or switched-neutral configurations.
Front face carries IP40 protection — fine for a dry indoor panel, not for washdown. No communication function — this is a straight electromechanical breaker, no Modbus or remote trip.
121 kA at 415 V AC. At 240 V it's 187 kA; at 440 V it drops to 75.6 kA. The high interrupting rating at common distribution voltages means it coordinates well with upstream transformers without requiring current-limiting fuses.
