420VAC/420VDC Fast-acting 5x20mm Fuse 487 Series New Product Introduction December 2014 1 487 Series 420VAC/VDC Fast-acting 5x20mm Fuse The 487 Series is the first fast-acting fuse from the Littelfuse 5x20mm fuse family with both AC and DC ratings Ensures best coordination 420VAC characteristics between a PSU (power supply make it well suited for high- unit) and an electrical circuit energy applications like 3- breaker panel during short-circuit phase power supplies, and over-current faults. inverters, and ballasts. Installs in PSU, trips faster 420VDC characteristics than a circuit breaker in an enable optimal performance electrical panel, removes the for high-voltage DC power problematic PSU from the branch grid in datacenters, telecom, circuit, and keeps the branch and intelligent commercial circuit live without cutoff. building applications.
