① Consult the nearest JOONGWON Sales Office for 50-hertz ratings. ② Asymmetrical and symmetrical ratings are given for each catalog number in each applicable system-voltage range. In each case, the asymmetrical rating is given first(in bold-face type) and symmetrical rating is given second(in light-face type). Rating in parentheses are the associated one-short rating(see Note *) ③ Nominal asymmetrical rating are based on total available short-circuit current of the circuit including the DC component, in accordance with IEEE standards. ④ Symmetrical rating assigned are based on available symmetrical short-circuit current at locations where X/R ratio is equal to 8 (for Cutout Catalog number 80420) or 12 (for all other overhead─pole-top style cutouts). IEEE C37.41-2000 specifies these X/R ratios, as applicable, depending on cutout voltage rating and interrupting current rating. ⑤ Uses either nonremovable or removable buttonhead fuse links. ⑥ Uses removable buttonhead fuse links only. ⑦ E - Extra heavy duty, U - Ultra heavy duty, H - Heavy duty. ● Applicable for protection of single-phase-to-neutral circuits (lines or transformers) only, and grounded-wye connected capacitor banks in solidly-grounded-neutral (multigrounded-neutral) systems─where the leakage distance to ground meets user’s requirements. ✽ One-shot rating, based on replacement of cutout tube only. ▲ Applicable for protection of single-phase-to-neutral circuits (lines or transformers) only, and grounded-wye connected capacitor banks in solidly-grounded-neutral (multigrounded-neutral) systems. + Meets 170-kV BIL rating requirement of IEC Publication 60282-2.
