Mounts in any position — no derating required for orientation — and accepts top or bottom feed through the combined terminals.
D-curve means the magnetic trip operates at 10–20× rated current (100–200 A for this 10 A unit), sized for loads with high inrush — motor starters, transformers, solenoid banks — where a B or C curve would nuisance-trip on startup. The 1-pole form factor interrupts only the phase conductor — neutral stays solid — so it's right for single-phase branch circuits or three-phase groups where you need individual pole protection without switching the neutral.
Temperature derating — the real-world current
The 10 A rating holds at 35 °C. Above that, the continuous current must be reduced: 9.39 A at 40 °C, 9.07 A at 45 °C, 8.74 A at 50 °C, 8.4 A at 55 °C, and 8.04 A at 60 °C. If the panel ambient runs warm — say 50 °C inside an enclosed cabinet — the breaker is good for 8.74 A continuous, not the full 10 A. That derating curve is the number to use when sizing the branch circuit.
Dual-rated to IEC/EN 60898-1 and IEC/EN 60947-2 / UL1077, so it qualifies for both household-type and industrial applications. IP20 with conductors connected. Halogen-free and silicon-free construction.
