Eaton's Bussmann Division fuses and surge circuit protection ...

LPJ系列 Class J 600Vac 慢速熔断器

The protection you rely on.

             The Bussmann brand continues to reflect a long-standing tradition of providing fusible circuit protection and electrical safety solutions that protect equipment and enable reliable, efficient power distribution.

             When you bring together the industry’s top innovator in fuse technology with unmatched expertise in circuit breakers you get leadership in circuit protection. Eaton’s heritage in circuit breaker development coupled with the number one Bussmann brand in fuses,means the choice is no longer fuse or breaker. Its fuse and breaker.

Features:

  • Industry’s only UL Listed and CSA Certified fuse with a 300kA 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.

  • Long time-delay minimizes needless fuse openings due to temporary overloads and transient surges.

  • Current-limitation protects downstream components against damaging thermal and magnetic effects of short-circuit currents.

  • Dual-element fuses have lower resistance than ordinary fuses so they run cooler. They can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail.

  • Proper sizing can provide “no damage” Type 2 coordinated protection for NEMA® and IEC® motor controllers.

  • Space-saving package for equipment downsizing.
