Product details

The D-curve holds through the starting surge of a motor or a welding transformer, so it won't nuisance-trip on the inrush.

Mounting & Integration

Mounting position is any, which helps when panel space is tight. The 70 mm installation depth and overall 76 mm depth mean it fits standard distribution boards without sticking past the cover.

Environmental & Compliance

Halogen-free and silicon-free — relevant for clean-room or semiconductor-adjacent installs where outgassing contaminates optics or wafers. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.
