Thermal derating and selectivity
At 35 °C the breaker carries its full 13 A; at 40 °C it derates to 12.38 A, at 50 °C to 11.73 A, and at 60 °C to 11.02 A — plan your load margin against the ambient inside the panel, not the 35 °C sticker rating.
Combined terminal at top and bottom accepts copper conductors; fastening via quick-assembly system (spring-cage or screw, depending on variant). Sealable, halogen-free, silicon-free — suitable for clean-room or food-beverage panels where outgassing or tamper evidence is required. AC supply polarity is arbitrary; DC supply must observe polarity marking on the device.
