Breaking capacity is rated at 10 kA per EN 60898 and 20 kA per IEC 60947-2, giving headroom for most residential and light commercial distribution boards where the prospective fault current stays under 10 kA. The supply cord can enter from either top or bottom, which speeds up wiring when the panel layout demands it.
Thermal derating and current selection
At 40 °C it derates to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A. For a panel running warm — say 45 °C internal ambient — the usable continuous current drops to 14.88 A, so factor that into the load calculation rather than relying on the 30 °C figure. It is the most commonly specified curve for residential and commercial final circuits in Europe.
Integration and physical fit
Halogen-free and silicon-free construction means the housing won't release corrosive halogens in a fire, which matters for equipment in ventilated enclosures or areas with sensitive electronics. Energy limitation class 3 indicates it limits let-through energy effectively for its rating.
