(see panelboard manufacturers literature for recommended fuse rating.) primary and secondary protection for transformers protection of power circuit breakers features and benefits eliminate unnecessary downtime klpc powr- pro series fuses time delay withstands system surges and keeps your circuits in service. best protection for system components maximum current limitation means less equipment and system damage when short circuits occur. reduced damage means that electrical service can be restored quickly, reducing costly downtime, and often permitting equipment repair rather than replacement. coordinates with other system components klpc series fuses provide maximum coordination with fuses and circuit breakers both on the line and load side of the fuses. see the fuseology section of this catalog for additional information. eliminate need to oversize fuses this may permit the use of smaller less expensive switches, and, since the lower rated fuses are more current limiting, equipment receives even better protection. 300ka interrupting rating littelfuse self-certified to 300,000 amperes as standard. meets future trend towards higher available short circuit currents.
