Overview

The Littelfuse SOO007, a robust dual-element time delay fuse, is engineered to provide superior protection for critical industrial and commercial electrical systems. As a Type S fuse, it is specifically designed for reliable motor and motor branch-circuit protection, a vital application where precise overcurrent management is paramount to prevent costly downtime and equipment damage. The dual-element construction is a key differentiator, offering a unique combination of fast-acting short-circuit protection and a time-delay characteristic for sustained inrush currents. This intelligent design minimizes nuisance tripping, a common issue with single-element fuses in motor applications, while still ensuring rapid response to dangerous fault conditions. Beyond its specialized motor protection capabilities, the SOO007 fuse also excels in general-purpose circuit protection, making it a versatile component for a wide array of applications. Its ability to safeguard diverse electrical loads underscores its value in maintaining operational integrity across various industrial settings, from manufacturing plants and processing facilities to commercial buildings and utility infrastructure. Littelfuse, a globally recognized leader in circuit protection, brings its extensive expertise and commitment to quality to the SOO007 series. When selecting fuses for motor circuits, professionals prioritize devices that can withstand the transient high currents associated with motor startup without sacrificing protection against sustained overloads or short circuits. The time-delay feature of the SOO007 fuse is crucial here, allowing the motor to start without tripping the fuse, yet providing immediate protection should a fault occur. This dual functionality is essential for maintaining productivity and extending the lifespan of electric motors and associated control gear. Furthermore, the Type S designation ensures compatibility with specific fuse holders, simplifying installation and replacement procedures within existing infrastructure. The SOO007 fuse is an ideal choice for applications demanding dependable performance, enhanced safety, and reduced maintenance. Key benefits and features of the Littelfuse SOO007 fuse include: * **Dual-Element Design:** Provides both fast-acting short-circuit protection and time-delay for motor starting currents, preventing nuisance tripping. * **Motor and Branch-Circuit Protection:** Specifically engineered for the demanding requirements of motor loads, ensuring optimal performance and safety. * **General Purpose Application:** Versatile enough to protect a wide range of other electrical circuits in industrial and commercial environments. * **Type S NEMA Rating:** Ensures proper fit and function with compatible Type S fuse holders. * **Littelfuse Quality:** Manufactured by a trusted industry leader with a reputation for reliability and innovation in circuit protection solutions. By choosing the Littelfuse SOO007 fuse, engineers and maintenance professionals can be confident in their ability to protect valuable assets, maintain operational continuity, and adhere to stringent safety standards. Its robust construction and advanced design make it a cornerstone for reliable electrical system protection.

Littelfuse Plug fuses provide overcurrent protection to general purpose circuits and small motor loads. Edison-base Plug fuses (TOO and TLO series) feature metal threads similar to incandescent lamp bases. Type S Plug fuses (SOO and SLO series) utilize a nonmetallic threaded base and must be used with Type S adapters (SAO series). The National Electrical Code permits Edison base Plug fuses to be used for replacement purposes only. Type S fuses and adapters prevent shunting open fuses and over-fusing.
