Description

LOW-PEAK CLASS J T/D

Features

  • Featuring a sophisticated dual-element construction with a minimum 10-second time-delay at 500% overload, the LPJ-3SP absorbs temporary current surges effortlessly. This performance is ideal for heavy industrial motors and transformers, preventing unnecessary system shutdowns while still delivering hyper-responsive short-circuit protection.
  • Rated for up to 600V AC and packing an industry-leading 300,000-amp interrupting rating (AIR), this space-saving Class J fuse provides maximum current-limiting performance. It rapidly isolates massive electrical faults to minimize downstream component damage, making it the premier choice for modern, high-short-circuit-current-rated (SCCR) industrial control panels.
  • Operating with advanced current-limiting capabilities, this fuse clears short-circuits faster than standard mechanical circuit breakers can react. By drastically restricting peak let-through energy (I^2t), it shields vulnerable variable speed drives (VFDs), solid-state relays, and PLCs from catastrophic thermal and magnetic destruction.
  • Measuring only 2.25 in times 0.81 in (57.2 times 20.6 mm), this 3-amp ferrule-style fuse provides robust 600V protection in a fraction of the space required by traditional Class R or Class H fuses. This compact architecture allows panel builders to use smaller, lower-cost fuse blocks and disconnect switches, saving premium real estate inside crowded control enclosures.
