Overview

The Littelfuse SOO014 is a high-performance dual-element time delay Type S fuse, meticulously engineered for the demanding protection requirements of motor and motor branch circuits. This fuse also excels in providing robust overcurrent protection for a wide array of general-purpose circuits, making it a versatile component in industrial and commercial electrical systems. Designed by Littelfuse, a globally recognized leader in circuit protection solutions, the SOO014 embodies reliability and advanced engineering. At its core, the SOO014 features a dual-element construction. This design incorporates both a short-circuit element and a time-delay element, offering superior protection against a broad spectrum of overcurrent conditions. The time-delay characteristic is crucial for motor applications, as it allows the fuse to withstand the temporary inrush currents associated with motor startup without nuisance tripping. This capability significantly enhances operational efficiency and reduces unnecessary downtime. Conversely, the fuse reacts swiftly to dangerous short-circuit conditions, providing rapid interruption and safeguarding sensitive equipment from catastrophic damage. Applications for the Littelfuse SOO014 are extensive. It is the ideal choice for protecting motors in HVAC systems, pumps, conveyors, and other industrial machinery. Its suitability for general-purpose circuits means it can be deployed in control panels, lighting circuits, and power distribution systems where reliable overcurrent protection is paramount. The Type S fuse design, when used with appropriate adapters (such as the SAO mentioned in related Littelfuse catalog entries for box cover units like LSOU, LSSU, and LSSY), ensures proper fuse installation and prevents the use of incorrect fuse ratings, further enhancing safety and system integrity. Littelfuse's commitment to quality is evident in the SOO014. These fuses are built to meet stringent industry standards, ensuring consistent performance and longevity even in harsh operating environments. By selecting Littelfuse SOO014 fuses, engineers and maintenance professionals can be confident in the protection of their valuable assets, minimizing the risk of equipment failure and costly repairs. Trust in Littelfuse for dependable, advanced circuit protection that keeps your operations running smoothly and safely.

Plug Fuse
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.
