open fuse indication

1 to 30A

35 to 60A

Features:

• Industry’s only UL Listed and CSA Certified fuse with a

300kA Vac interrupting rating that exceeds requirements for

virtually all applications

• Long time-delay minimizes needless fuse openings due to

temporary overloads and transient surges

Description: Ultra protection Class J dual element, current-

limiting, time-delay fuses available with optional open fuse in-

dication. Time-delay – 10 seconds (minimum) at 500% of

rated current.

• Easy selective coordination with all Low-Peak fuses using

simple 2:1 ampacity ratio

• Can often be sized for back-up protection against motor

burnout from overload or single-phasing if other overload

protective devices fail

• High degree of current limitation due to the fast speed-of-

response to short-circuits

Catalog Symbol: LPJ-(amp)SP (non-indicating)

LPJ-(amp)SPI (indicating)

Ratings:

Volts — 600Vac, 300Vdc

Amps — 1-60A

• Faster response to damaging short-circuit currents than

mechanical overcurrent protective devices

IR — 300kA Vac RMS Sym.

— 100kA Vdc

• 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

Agency Information:

CE, UL Listed, Guide JDDZ, File E4273

• Dual-element fuses have lower resistance than ordinary

fuses so they run cooler

• Lower watts loss reduces power consumption

• Space-saving package for equipment downsizing

CSA Certified, Class 1422-02, File 53787,

Class J per CSA 22.2 No. 248.
