At 15 kA DC per the same standard, it also handles DC bus faults in drives or rectifier sections.
Fit and integration into a panel
Width is 18 mm — one modular unit on a DIN rail. Fastening is via the quick-assembly system, which clips onto the rail without tools.
Temperature derating and ambient conditions
Rated 2 A at 45 °C, derates to 1.95 A at 50 °C, and 1.9 A at 55 °C. Ambient range is -40 °C to 75 °C, with humidity influence capped at 95% up to 55 °C, 55% up to 70 °C, and 35% up to 75 °C. If your panel runs hot near a drive or transformer, use the 55 °C figure — 1.9 A — as the continuous limit, not the catalog 2 A. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz.
Approvals and compliance documentation
Rated breaking capacity of 5 kA per UL 1077 and CSA C22.2 No. 235 for North American acceptance. Halogen-free and silicon-free construction — important for clean-room or semiconductor fab environments where outgassing contaminates optics or wafers. Sealable terminals allow tamper-proofing after commissioning. Touch protection is integrated. The product designation per IEC 81346-2 and DIN EN 61346-2 is F (protective device).
