Interrupting Rating: 200,000 RMS Symmetrical Amps
Current Limiting:
Class J Fuse
EDISON JFL Class J fuses are among the most current lim-
iting fuses available. Their small physical size and high per-
formance characteristics makes Class J fuses ideal for any
space - limited application.
Agency Approvals:
UL Listed, Class J, Guide JDDZ, File E162363
CSA Certified HRCI-J per C22.2, No. 248.8
Self-Certified DC Ratings:
Voltage Rating:
EDISON JFL fuses are best suited for the protection of non-
inductive loads such as resistive heating, and lighting cir-
cuits.
JFL (1-30A) 200VDC
JFL (35-60A) 175VDC
JFL (70-600A) 300VDC
Interrupting Rating: 20,000 Amperes DC
BENEFITS:
RECOMMENDED FUSEBLOCKS:
• Space saving dimensions vs Class R.
• Fast-Acting design permits quick response for both over-
loads and shorts.
Refer to page 137 in this catalog.
RECOMMENDED UPGRADE:
JDL.
• Extremely current-limiting.
APPLICATIONS:
• Recommended for protection of non-inductive loads, such
as lighting and resistance heating circuits.
• For motor applications, refer to EDISON JDL.
