Rated 0.5 A at 45 °C and derated to 0.49 A at 50 °C and 0.47 A at 55 °C, so if the enclosure runs warm, the actual continuous current it can carry drops; factor that into the load calculation if the panel is in a hot cabinet.
Breaking capacity and selectivity in a real panel
The 70 kA rating per IEC 60947-2 is the headline number, but the part also carries a 15 kA DC breaking capacity per the same standard and a 5 kA rating per UL 1077 and CSA C22.2 No. 235 — so it's certified for both IEC and North American panels, though the UL/CSA rating is lower and governs any listing in those jurisdictions. Vibration resistance tested to IEC 60068-2-6 at ±1 mm from 5 to 25 Hz and 50 m/s² from 25 to 150 Hz, so it holds up on a machine frame or in a mobile equipment panel, not just a stationary wall-mount board.
Integration into a panel — dimensions and wiring
Width is 72 mm (4 modular units), height 90 mm, depth 76 mm, installation depth 70 mm. Combined terminals on both top and bottom accept the same conductor range, and the part is sealable — useful for applications where the panel must be locked after commissioning to prevent tampering. Halogen-free and silicon-free construction matters in environments where outgassing from a fault could contaminate optics or electronics — think semiconductor fabs, medical device manufacturing, or cleanroom-adjacent panels.
