It carries a 50 kA breaking capacity at 400 V AC per IEC 60947-2, and is also rated for 15 kA at 60 V DC per the same standard.
The C-curve (tripping characteristic class C) means magnetic trip between 5x and 10x In — standard for motor circuits, small transformers, and lighting where inrush isn't extreme but higher than a B-curve handles. The DC rating of 15 kA at 60 V covers common 48 V and 60 V control bus protection. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — it'll hold up on a conveyor drive panel or a pump skid without nuisance tripping from line vibration.
Mounting position is any, so you can lay it sideways in a shallow enclosure if needed. Temperature range is -40 to 75 °C, so it's fine in unheated warehouses or near a hot motor starter.
