Description: Fast-acting, bolt-mount fuse.
Ratings:
Volts: 600Vac (or less)
Amps: 601-6000A
IR: 200kA RMS Sym.
Agency Information: CE, Std. 248-10, Class L, UL Listed, Guide JDDZ, File E4273
CSA Certified, Class 1422-02, File 53787.
General Information:
* Fast-acting, short-circuit protection. Particularly suited for protection of
circuit breakers with lower interrupting ratings and non-inductive loads such as
lighting and heating circuits.
* 99.9% pure silver-links provide low watt loss and low operating temperature on
normal current levels; minmizes total clearing I2t fault energy let-through.
* High grade silica-sand filler accelerates response of fuse to short-circuits
by having a quenching effect upon the fuse arc.
* O-ring seals maximize pressure build-up during currentlimiting actions and
ensure filler retention.
* Silver-plated micro-peened terminals provide high electrical conductivity,
minimize heat generation, and keep fuses and switches cool.
* UL interrupting rating of 200,000 amperes.
* Selective coordination (blackout prevention).
* Glass melamine tube.
* Silver-plated end bells.
* No fuse reducers available.
Features and Benefits
* 200kA interrupting rating provides high ratings at all circuit locations.
* Economical solutions for high-fault circuits.
* Quality construction using high-grade materials provides lower watts loss and
operating temperatures with superior arc quenching during current-limiting
action.
Typical Applications
* Large Distribution Switchboards
* Power Panelboards
For superior electrical protection, Cooper Bussmann recommends upgrading KTU
fuse applications to Low-Peak KRP-C fuses
