Partial-range protection fuse (aR) with low I²t, strong current limitation and high breaking capacity. For rail transit, electric vehicles, ships and other industries: short-circuit backup protection of energy storage systems, power systems, conductors and other equipment.

DC 1500 V · 100 to 450 A · aR · 250 kA (time constant ≤ 5 ms) · IEC 60269-4, UL 248-13 · UL, TÜV · RoHS. Minimum breaking current 5 In.

Size 3, two terminal versions with identical electrical values: RAZ offset blade terminals, bolt M8, 11 ± 1 N·m (211 ± 2.5 mm overall); QAZ in-line blade terminals, bolt M10, 21 ± 1 N·m (210 ± 2.5 mm overall). Body 74 × 74 mm. Listed references carry a visual indicator on the base (switch mountable); add -N for no indicator. 2250 ± 200 g, 3 to 6 per package. Mounting surface coplanarity 0.5.

Standard test conditions 20 °C, altitude ≤ 2000 m, still air. Ambient −40 °C to +100 °C and altitude up to 5000 m, with rated current corrected for temperature, altitude, forced cooling and conductor cross-section. Square fuses: pollution degree 2 (Sinofuse datasheet ZR/YC-0858 S1, 14/05/2025). The 630 A rating is outside this datasheet.
