Breaking capacity and what it means for your panel
This breaker is rated 10 kA per EN 60898 and 35 kA per IEC 60947-2 at 400 V AC. The EN 60898 number is the standard household/commercial rating; the IEC 60947-2 figure is the industrial rating that matters when the breaker sits downstream of a high-fault transformer or in a panel with high available fault current. For DC circuits, it handles 15 kA per IEC 60947-2 up to 72 V — useful for battery-backed control circuits or DC bus protection. The 35 kA industrial rating gives you selectivity headroom without needing a current-limiting upstream device in many common panel configurations.
Terminal and wiring details
The combined terminals (top and bottom) accept solid or stranded conductors from 0.75 mm² up to 35 mm² — that covers everything from small signal wiring to fairly heavy feeder tails. The terminals are sealable, and the breaker is halogen-free and silicon-free, so it's safe for clean-room or sensitive electronic environments where outgassing matters. Touch protection is built in, reducing the risk of accidental contact during panel work.
Environmental and mounting flexibility
Ambient temperature range is -40 to +70 °C, with a storage range of -40 to +75 °C. That covers most indoor industrial environments and even unheated enclosures in cold climates. Mounting position is any, and the power supply cord position is any — so you can orient the breaker vertically, horizontally, or upside-down without derating. Overvoltage category III means it's rated for fixed installations downstream of the main distribution board, not just final circuits.
