It switches the neutral conductor, making it suitable for single-phase final circuits where both phase and neutral need overcurrent protection and isolation. The C-curve (5–10× In) handles moderate inrush from lighting banks, small transformers, and motorized loads without nuisance tripping.
Mounting position is any — vertical or horizontal orientation is acceptable. Terminal design accepts both top and bottom feed without a combined terminal, so line and load wiring are separate entries.
Thermal and environmental limits
Rated 32 A at 30 °C ambient; derates to 30.4 A at 40 °C and 29.76 A at 45 °C. The storage temperature range spans -40 to 75 °C, and operating humidity is limited to 85% rF up to 45 °C, dropping to 43% rF between 45 and 60 °C. Halogen-free and silicon-free construction suits sensitive environments like data centers or medical equipment rooms.
