Product details

At 8 A, it handles sustained loads up to that figure; above that, the magnetic trip reacts fast. Breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No.235.

The 8 A rating holds at 35 °C ambient. At 40 °C it derates to 7.35 A, at 45 °C to 7 A, at 50 °C to 6.63 A, and at 55 °C to 6.25 A. If the panel runs hot, size up one frame to keep the trip point above your load current. Mounts via quick assembly system (snap-on DIN rail) in any position.

Halogen-free and silicon-free construction. Sealable for tamper-proof installations. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. The product designation per IEC 81346-2 and DIN EN 61346-2 is F.
