Overview

The Littelfuse LMF005.UL Time Delay Inline Fuse with Knob & Holder Assembly delivers reliable overcurrent protection for industrial electrical systems, available in a cost-effective 500-pack bulk configuration. Designed to safeguard sensitive equipment against damaging fault currents while accommodating temporary inrush conditions, this fuse assembly is a trusted choice for professionals in manufacturing, automation, and power distribution. The time delay characteristic allows it to handle brief overloads common in motor starting, transformer energization, and inductive load switching without nuisance tripping, ensuring uninterrupted operation of critical processes. Engineered for durability and ease of use, the LMF005.UL features a robust knob and holder assembly that simplifies installation, replacement, and maintenance in demanding environments. The inline design provides flexible mounting options, making it ideal for control panels, machinery enclosures, and distribution boards where space efficiency is paramount. Unlike standard fast-acting fuses, the time delay version offers superior protection for inductive loads by allowing brief current surges while still interrupting sustained overcurrents that could damage wiring or components. Typical applications include: - Motor branch circuits in industrial machinery - Transformer primary and secondary protection - Power supply inrush current mitigation - Control circuit protection in automation systems - HVAC and refrigeration equipment The 500-pack bulk packaging ensures procurement efficiency for facilities requiring large quantities of fuses, reducing stock management overhead while maintaining consistent protection standards across multiple installations. Littelfuse's reputation for high-quality circuit protection products stems from decades of innovation in fuse technology, with the LMF005.UL meeting UL safety standards for reliable performance in commercial and industrial applications. The UL-listed designation confirms compliance with rigorous safety and performance requirements, giving engineers and maintenance teams confidence in the product's suitability for mission-critical systems. Professionals select time delay fuses like the LMF005.UL when protecting equipment with high inrush currents or when coordinating with other protective devices in a system. The inline configuration with integrated holder eliminates the need for separate mounting hardware, streamlining both initial installation and subsequent maintenance. For facilities operating in harsh environments, the fuse's design provides resistance to vibration and mechanical stress while maintaining electrical integrity. Whether used in new installations or as replacement components in existing systems, the Littelfuse LMF005.UL offers a balance of protection, convenience, and value that makes it a preferred choice for industrial electrical protection applications.
