It's rated 400 V AC and carries a 10 kA breaking capacity per EN 60898, with a higher 15 kA rating per IEC 60947-2 for industrial coordination. The D-curve means it's built for loads with high inrush — motor starters, transformers, or welding equipment — where the magnetic trip is set to hold through the start surge and clear a hard fault. The wide -40 to 75 °C operating range covers unheated storage areas and hot panel interiors alike.
Panel fit and environmental ratings
Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 sec). That covers most rotating machinery and conveyor line applications without needing additional damping. The sealable design allows panel builders to lock the handle position after commissioning — useful for preventing unauthorized reset on a safety-critical circuit.
