What this C-curve 1P+N MCB does on the line
Breaking capacity sits at 10 kA per IEC 60898-1 and 20 kA per IEC 60947-2, with 15 kA at DC per IEC 60947-2 and 5 kA under UL 1077. That dual-rating matters: the 20 kA figure under 60947-2 is the one your panel SCCR study uses when the breaker is listed as a branch-circuit protective device; the 10 kA figure is the domestic / commercial rating under the MCB standard. At DC, the 15 kA rating at 60 V (max 72 V) covers battery-backed control circuits and DC bus taps in industrial automation. Rated operational voltage is 230 V AC single-phase (250 V max single-phase) and 60 V DC. The neutral conductor is switched internally, so this breaker isolates both poles when tripped — important for maintenance lockout on single-phase loads where you need confirmed isolation of the neutral, not just the phase.
Any mounting position accepted, and the supply cord can enter from any direction, which simplifies wiring in crowded cabinets. Ambient range -40 °C to 75 °C, but the surrounding temperature influences the thermal trip: max 95% RH at 55 °C, derating to 55% at 70 °C and 35% at 75 °C. In a sealed panel near heat sources, factor that humidity limit — condensation at high temp + high humidity can affect the bimetal calibration over time. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in clean-room or sealed electronics cabinets. Sealable terminals (combined top and bottom) allow the panel builder to lock the cover after commissioning, preventing unauthorized access to the live connections.
