Overview

The Littelfuse 229 Series 2AG Slo-Blo® Fuse (SKU: H23002.5P) represents a significant advancement in compact overcurrent protection, delivering the robust performance of traditional 3AG fuses in a footprint that is less than one-third the size. Engineered for demanding industrial applications, this 2.5A fuse is specifically designed to safeguard sensitive inductive loads, including motors, transformers, and solenoids, from damaging surges and faults. Its time-delay characteristic is crucial for circuits that experience temporary inrush currents during startup, preventing nuisance tripping while ensuring reliable protection against sustained overloads. Crafted with a durable glass body and featuring convenient axial leads, the 229 Series fuse offers ease of integration into a wide range of electronic and electrical systems. The 2AG form factor is ideal for space-constrained designs where performance cannot be compromised. Professionals rely on Littelfuse for their unwavering commitment to quality and innovation, and this fuse is a testament to that legacy. The time-delay functionality, often referred to as "slow-blow," is essential for applications where a brief surge of current is normal, such as powering up a motor or energizing a transformer. Without this feature, standard "fast-acting" fuses would repeatedly blow during normal operation, leading to costly downtime and maintenance. Beyond its core protective capabilities, Littelfuse also offers an indicating version of the 2AG fuse. This advanced variant provides an immediate visual cue – a discoloration of the glass body – upon activation. This feature dramatically simplifies troubleshooting, allowing technicians to quickly identify a blown fuse without the need for time-consuming circuit testing or guesswork. This rapid identification capability is invaluable in industrial settings where minimizing downtime is paramount to maintaining productivity and profitability. The consistent performance and reliability of Littelfuse fuses ensure that your critical equipment is always protected, adhering to stringent industry standards and providing peace of mind. Key Features and Benefits: * **Compact 2AG Form Factor:** Occupies significantly less space than traditional 3AG fuses, enabling smaller and more efficient equipment designs. * **2.5A Current Rating:** Precisely calibrated for applications requiring specific overcurrent protection levels. * **Time-Delay (Slo-Blo®) Operation:** Ideal for protecting inductive loads by allowing for inrush current without nuisance tripping. * **Axial Leads:** Facilitates easy and secure mounting in various circuit configurations. * **Durable Glass Body Construction:** Ensures robust performance and visual inspection capabilities. * **Superior Inductive Load Protection:** Specifically engineered for motors, transformers, solenoids, and other components prone to current surges. * **Optional Indicating Version:** Instantly identifies blown fuses through visual discoloration, reducing troubleshooting time and costs. * **Trusted Littelfuse Quality:** Manufactured by a leading global provider of circuit protection solutions, ensuring reliability and performance. When selecting fuses for critical industrial applications, the Littelfuse 229 Series 2AG Slo-Blo® Fuse stands out as a superior choice for its combination of compact size, advanced time-delay characteristics, and robust protection for inductive loads. Its availability in both standard and indicating versions further enhances its utility, making it a versatile component for a wide array of electrical and electronic systems.
