Type A means it responds to AC residual currents plus pulsed DC, covering modern electronics with half-wave rectification. Short-time delayed design means it holds through transient leakage pulses up to 3 kA surge current without nuisance tripping, which is critical when feeding downstream equipment with capacitive inrush or surge suppressors.
No end-of-life notice or successor has been published. If you're freezing a BOM, this is a safe line-item with no imminent LTB risk.
Silicon-free construction is noted for applications where silicone outgassing can contaminate contacts or optics.
Above that, derate: 77.87 A at 45 °C, 74.77 A at 50 °C, 70.26 A at 55 °C, 64.32 A at 60 °C, 56.96 A at 65 °C, and 48.2 A at 70 °C (–). Short-circuit current rating is 10 kA per IEC 61008-1 and 0.8 kA per EN 60898 — the EN figure governs domestic consumer-unit coordination; the 10 kA figure applies in industrial distribution boards with higher fault capacity. Let-through energy is rated at 110,000 A²·s, and the permissible let-through current is 7,100 A — useful for selectivity calculations with downstream MCBs.
