The 5SY4304-5: Certified to IEC/EN 60898-1 for residential and commercial distribution, and to IEC/EN 60947-2 / UL1077 for industrial control-panel applications — the dual rating means the same part serves both a lighting panel and a machine control cabinet without a separate UL 489 listing.
The 5SY4304-5 has a Type A tripping characteristic — instantaneous trip between 2 and 3 times rated current, designed for semiconductor protection and DC-load circuits where standard B or C curves would cause nuisance tripping.
