Overview

The **Littelfuse 2AG Slo-Blo® Fuse (SKU: H230002P)** is a high-performance, time-delay fuse engineered for superior protection of inductive loads in industrial and commercial applications. Designed to replace bulkier 3AG fuses while delivering identical performance in a compact 2AG form factor, this fuse occupies less than one-third the space of traditional alternatives—making it ideal for space-constrained panels, control systems, and equipment where every millimeter counts. Engineered for **2A current rating**, the 229 Series Slo-Blo® fuse provides **time-delay protection**, allowing brief inrush currents typical of motors, transformers, solenoids, and other inductive loads to pass without nuisance tripping. This critical feature ensures reliable operation in applications where transient surges are common, such as HVAC systems, industrial machinery, power supplies, and automation equipment. Unlike standard fast-acting fuses, the Slo-Blo® design prevents false openings during startup or overload conditions, reducing unplanned downtime and maintenance costs. Available in a **clear glass body with axial leads**, the fuse offers **easy visual inspection** and compatibility with standard fuse holders. Its **2AG size** (5mm x 20mm) ensures broad compatibility across a wide range of fuse blocks and panels, while the **glass construction** provides robust dielectric strength and thermal stability. For applications requiring immediate fault identification, Littelfuse offers an **indicating version** of this fuse, which discolors upon opening—eliminating guesswork during troubleshooting and accelerating repair processes. Littelfuse, a global leader in circuit protection solutions, has built a reputation for reliability, innovation, and precision engineering. The **229 Series Slo-Blo® Fuse** exemplifies this commitment, combining decades of fuse design expertise with rigorous testing to meet UL, CSA, and other international standards. Professionals across industries—from manufacturing and energy to telecommunications and automotive—trust Littelfuse for dependable protection against overcurrent events, ensuring operational continuity and equipment longevity. **Key Applications:** - **Motors and motor starters** (single-phase and three-phase) - **Transformers and power supplies** (including SMPS and industrial chargers) - **Solenoids and relays** in control panels - **HVAC systems** (compressors, fans, and pumps) - **Industrial automation** (PLCs, sensors, and actuators) **Installation and Selection Considerations:** When selecting a fuse for inductive loads, engineers must balance **time-delay characteristics** with **interrupting rating** and **physical constraints**. The 2AG Slo-Blo® fuse is optimized for **low-voltage AC/DC circuits** up to 250V, with a **2A rating** suitable for circuits where steady-state current is 2A or less. For higher inrush currents, consult Littelfuse’s **time-current curves** to ensure proper coordination. The axial lead design simplifies installation in PCBs or chassis-mounted fuse holders, while the glass body allows for quick visual confirmation of fuse status. **Why Choose Littelfuse?** With over a century of innovation in circuit protection, Littelfuse delivers products that meet the demands of modern industrial environments. The **229 Series Slo-Blo® Fuse** is backed by comprehensive technical support, global distribution, and a commitment to quality that reduces risk in critical applications. Whether you’re designing a new system or maintaining existing equipment, trust Littelfuse to provide the protection your circuits deserve.
