Dual-rated to IEC/EN 60898-1 and IEC/EN 60947-2 / UL1077, the 5SY4315-5 carries approvals for both residential-style and industrial applications. The UL1077 listing (5 kA at AC) covers North American supplementary protection use. Rated insulation voltage is 440 V AC for both single-phase and multi-phase operation, with a DC rating of 60 V (72 V max).
10 kA per EN 60898-1 and 35 kA per IEC 60947-2 at 400 V AC. At DC (60 V) it is rated 15 kA per IEC 60947-2.
Characteristic A trips magnetically at 2 to 3 times rated current. It is faster than B-curve (3-5×) and C-curve (5-10×), making it suitable for protecting sensitive loads like semiconductor circuits or long cable runs where fast fault clearing is needed.
