Limitron® fuses,KTU Class L

 

KTU Class L
Specifications
Decription:
Fast-acting, bolt-mount fuse.
Ratings:
Volts- 600Vac (or less)
Amps- 601-6000A
IR- 200,000A RMS Sym.
Agency Information:
CE, Std. 248-10, Class L, UL Listed, Guide JDDZ, File E4273 CSA Certified, Class 1422-02, File 53787.
Features and Benefits:
@ 200,000A 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
Note:
For superior electrical protection, Cooper Bussmann recommends upgrading KTU fuse applications to Low-Peak KRP-C fuses.
