Overview

The Littelfuse 0313025.MXP is a high-quality 25A Slo-Blo® glass fuse designed to provide robust and reliable circuit protection for a wide array of demanding industrial applications. Manufactured by Littelfuse, a globally recognized leader in circuit protection solutions, this 3AG fuse offers a cost-effective yet exceptionally performant method for safeguarding electrical systems against overcurrents and short circuits. Engineered as part of the 313 and 315 series, this Slo-Blo fuse features time-delayed characteristics specifically within the overload range. This critical design element makes it ideally suited for protecting inductive loads, which are common in industrial settings. Inductive components such as motors, transformers, and solenoids inherently generate inrush currents when initially energized. A fast-acting fuse would often nuisance-trip under these normal operating conditions. The time-delayed nature of the Littelfuse 0313025.MXP allows it to withstand these temporary current surges while still providing rapid protection against sustained overloads and damaging short circuits, thereby preventing equipment failure and minimizing downtime. A standout feature of this particular Littelfuse fuse is its indicating capability. The glass body is designed to visibly discolor upon activation, providing an immediate and unambiguous visual indication that the fuse has blown. This eliminates the need for time-consuming and often frustrating circuit testing to identify a faulty fuse. Maintenance personnel can quickly and accurately pinpoint the source of an electrical fault, significantly reducing diagnostic time and accelerating the restoration of operational status. This feature is invaluable in busy industrial environments where swift problem resolution is paramount. Key benefits and features of the Littelfuse 0313025.MXP include: * **Time-Delayed Overload Protection:** Superior performance for inductive loads like motors, transformers, and solenoids, preventing nuisance tripping while ensuring protection. * **Instant Visual Indication:** Discoloration of the glass body clearly signals a blown fuse, simplifying troubleshooting and reducing downtime. * **Reliable Circuit Protection:** Safeguards sensitive electrical components and equipment from damaging overcurrents and short circuits. * **Cost-Effective Solution:** Offers excellent performance and protection at an economical price point. * **3AG Form Factor:** A standard and widely compatible fuse size for easy integration into existing systems. * **Littelfuse Quality:** Manufactured by a trusted industry leader with a reputation for dependable circuit protection devices. This 25A Slo-Blo glass fuse is an essential component for maintaining the integrity and operational efficiency of industrial machinery, control panels, power supplies, and various other electrical systems. Its combination of advanced protection features, ease of identification, and the trusted Littelfuse brand makes it a preferred choice for engineers and maintenance professionals seeking reliable and efficient circuit protection solutions. The UNSPSC code for this product is 39121627, categorizing it under fuses.
