Dual-Element Time-Delay Fuses
Class J – 600 Volt
6-60 Amps
General Information:
• Permanent fuse Indication.
Dimensional Data
2.25"
(± 0.03)
• True dual-element fuses with a minimum 10 second time-
delay at 500% overload.
• Long time-delay minimizes needless fuse openings due to
temporary overloads and transient surges.
.81"
(± 0.03)
.5"
1A to 30A
• Can often be sized for back-up protection against motor
burnout from overload or single-phasing if other overload
protective devices fail.
• High interrupting rating to safely interrupt overcurrents up to
300,000A.
2.38"
(± 0.03)
.63"
1.06"
35A to 60A
• High degree of current limitation due to the fast speed-of-
response to short-circuits.
(± 0.03)
• Faster response to damaging short-circuit currents than
mechanical overcurrent protective devices.
• Reduces let-through thermal and magnetic forces in order
to protect low withstand rated components.
• Proper sizing provides “no damage” Type “2” coordinated
protection for NEMA and IEC motor control in accordance
with IEC Standard 947-4-1.
• Dual-element fuses have lower resistance than ordinary fuses
so they run cooler.
• Lower watts loss reduces power consumption.
• Unique dimensions assure that another class of fuse with
a lesser voltage rating, interrupting rating or current-Iimiting
ability cannot be substituted.
