The C-curve (5–10× In) is the standard pick for motor starters, small transformers, and general branch circuits where a moderate inrush won't nuisance-trip.
Fit and mounting
Depth is 76 mm (70 mm installation depth), so it clears standard 80 mm deep enclosures.
Dual-rated to IEC/EN 60898-2 and UL 1077, which means it's accepted for both IEC-style distribution boards and UL-recognized supplementary protection. Halogen-free and silicon-free construction — no silicone outgassing to foul contacts in sealed panels. Ambient operating range -40 °C to 75 °C, with humidity derating above 55 °C (95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.
