Their small physical size and high performance characteristics makes Class J fuses ideal for any space - limited application. EDISON JFL fuses are best suited for the protection of noninductive loads such as resistive heating, and lighting circuits. BENEFITS: • Space saving dimensions vs Class R. • Fast-Acting design permits quick response for both overloads and shorts. • 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. 20 Voltage Rating: JFL - 600VAC Ampere Rating: 1 - 600 Amps Interrupting Rating: 200,000 RMS Symmetrical Amps Current Limiting: Class J Fuse 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: JFL (1-30A) 200VDC JFL (35-60A) 175VDC JFL (70-600A) 300VDC Interrupting Rating: 20,000 Amperes DC RECOMMENDED FUSEBLOCKS: Refer to page 137 in this catalog.
