Shawmut ATS-DE500R Fuse

Shawmut ATS-DE500R is a Ferraz Shawmut Amp-Trap dual-element time-delay fuse rated for 500 A at 600 V, specifically engineered for RK5 protection in low-voltage power networks; it sits in the Amp-Trap family as a compact, reliable protection device designed to interrupt fault currents while tolerating short, non-fault overloads. The ATS-DE500R designation carries the 500 A/600 V specification and denotes a dual-element time-delay construction that combines fast response to sustained faults with built-in tolerance to brief inrush or transient overcurrents common in distribution feeders. As an RK5-class fuse, it is intended for protection schemes across distribution circuits and equipment in industrial and commercial electrical systems where predictable coordination and fail-safe fault clearing at the 500 A level are required. Belonging to Ferraz Shawmut's Amp-Trap lineup, the ATS-DE500R delivers established performance in low-voltage protection applications and offers a standardized part number for easy cross-referencing with catalogs and replacement parts.
