* Open fuse indication available by inserting the suffix “I ," e.g. LPN-RK-50SPI. Requires 75Vac minimum voltage. Indicating fuses are not Vdc rated.
* Open fuse indication available on all part numbers by inserting the suffix “I ," e.g., LPN-RK-90SPI. Requires 75Vac minimum voltage. Indicating fuses are not Vdc rated.
Typical applications
• Feeder and branch circuits
• Transformers
• Motors
• Solenoids
• General purpose circuits
Features and benefits
• Industry's only UL Listed and CSA Certified fuse with a 300 kA interrupting rating that allows for simple, worry-free installation in virtually any application.
• Fast short-circuit protection and dual-element, time-delay performance provide ultimate protection. • Reduces existing fuse inventory by up to 33% when upgrading to Low-Peak fuses. • Consistent 2:1 ampacity ratios for all Low-Peak fuses make selective coordination easy.
• Time-delay permits 130% FLA sizing for back-up motor protection.
• Current-limitation protects downstream components against damaging thermal and magnetic effects of short-circuit currents.
• Protects against single-phase motor damage.
• Proper sizing can provide “no damage” Type 2 coordinated protection for NEMA and IEC motor controllers.
