【文字介绍】

In contrast with existing fuse solutions that cannot meet high-voltage and short-circuit test requirements, the 5x20mm 487 Series Fuse protects telecom power supply units and datacenter server power applications where a high-voltage DC interrupting rating is required. This compact ceramic body fuse is designed to ensure the best coordination between a power supply unit (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 the branch circuit live without cutoff.
