EDISON JFL Class J fuses are among the most current limiting fuses available. 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.

RMS SYMMETRICAL CURRENTS IN AMPERES
A–B=ASYMMETRICAL AVAILABLE PEAK (2.3 X SYMM RMS AMPS)
* Curves test data obtained at 15% short-circuit power factor when possible.
** "Apparent Let-Thru Amperes" values are read from "Peak Let-Through Current Curves" and the peak current value divided by 2.3 Asymmetry Factor.
