Limitron® fast-acting fuses,JKS Class J

Low Voltage, Branch Circuit Rated Fuses - Branch Circuit Rated Fuses
Limitron® fast-acting fuses

 

JKS Class J
Specifications
Decription:
Fast-acting, current-limiting fuse.
Ratings:
Volts- 600Vac (or less)
Amps- 1-600A
IR- 200,000A RMS Sym.
Agency Information:
CE, Std. 248-8, Class J, UL Listed, Guide JDDZ, File E4273, CSA Certified, Class 1422-02, File 53787.
Features and Benefits:
@ Current limitation for non-inductive circuits provides Class J current-limiting response to maximum ground fault and short-circuit conditions.
@ 200,000A interrupting rating provides high ratings at all
circuit locations.
@ Economical solutions for high-fault circuits.
Typical Applications:
@ Power Panelboards
@ Machinery Disconnects
Note:
For superior electrical protection, Cooper Bussmann recommends upgrading JKS fuse applications to Low-Peak LPJ fuses.
