†Meets all performance requirements of UL Standard 248-8 for Class J fuses.
General Information:
• Permanent replacement fuse indication.
• 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.
• 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.
• High degree of current-limitation due to the fast speed-of-
response to short-circuits.
• 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.

Recommended fuseblocks for
Class J 600V fuses
See Data Sheet: 1114
• Dual-element fuses have lower resistance than ordinary
fuses, hence 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.
For non-indicating version, the LPJ_SP
is available. See Data Sheet: 1007.
• Space-saving package for equipment down sizing.
CE logo denotes compliance with European Union Low Voltage Directive
(50-1000Vac, 75-1500Vdc). Refer to Data Sheet: 8002 or contact
