The fuse comes with current ratings as high as 16A and in a 5x20mm space-saving compact ceramic body. It ensures the best coordination between a PSU and an electrical circuit breaker panel during short-circuit and over-current faults.
When installed in a PSU, the 487 Series fuse opens faster than the circuit breaker in an electrical panel, removes the problematic PSU from the branch circuit, and keeps it live without cut-off. The fuse’s 420VAC characteristics make it ideal for high-energy applications like 3-phase power supplies, inverters and ballasts.
With 420VDC characteristics, the fuses are an optimal choice for a high-voltage DC power grid in datacenters, telecom, and intelligent commercial buildings.
