Instantaneous response — no intentional short-time delay — so it clears fast on a ground fault. Feed from top or bottom; mounting position any orientation.
Derate linearly above 40 °C: 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, 48.2 A at 70 °C. If the distribution board runs hot, the 5SV3317-6 still carries load but the headroom shrinks. The short-circuit current rating (SCCR) is 10 kA per IEC 61008-1 and 0.8 kA per EN 60898 — the 10 kA figure governs the fault-clearing capability at the RCCB's terminals; the 0.8 kA is the conditional rating when backed by an upstream overcurrent device. Surge current resistance rated 1 kA, I²t let-through 110 000 A²s. Type A residual current detection covers sinusoidal AC and pulsed DC faults up to 30 mA — standard for circuits with rectified loads (washing machines, LED drivers, EV chargers).
The 70 mm installation depth matches standard distribution board enclosures; no extra clearance needed behind the rail. IP20 with connected conductors in an installed distribution board — not rated for wet or dusty environments. Overvoltage category III, suitable for fixed-installation downstream of the service entrance. Silicon-free construction, which matters for potting or conformal-coating processes in sensitive electronics panels.
