Littelfuse 229002P - SLO-BLO 2AG TYPE GLASS FUSE 2A. The 2AG Slo-Blo® Fuses are available in cartridge form or with axial leads. 2AG Fuses providing the same performance characteristics as their 3AG counterpart, while occupying one-third the space. Features: 229 series 2AG fuses have time-delay of 313 series 3AG fuses in less than one-third of the space. They provide superior protection for inductive loads such as motors, transformers, and solenoids. Use whenever time-delay fuses are indicated. An indicating version is also available. 2AG indicating fuses instantly identify themselves upon opening by showing a discoloration of their glass bodies. Guesswork and time-consuming circuit testing is eliminated. This unique design offers the same quality performance characteristics as the standard 2AG fuse design.

Overview

The **Littelfuse 229002P SLO-BLO 2AG TYPE G Glass Fuse** is a high-performance, time-delay fuse engineered for robust protection of inductive loads in industrial and electronic circuits. Part of the trusted **229 Series**, this **2A fuse** delivers the same reliable performance as larger 3AG fuses while occupying **less than one-third the space**, making it ideal for space-constrained applications. Available in both **axial lead and cartridge configurations**, the 229002P ensures consistent overcurrent protection while minimizing installation footprint, a critical advantage in modern panel designs and compact machinery. Littelfuse’s **SLO-BLO® technology** provides a deliberate time delay, allowing temporary current surges—common in motors, transformers, and solenoids—to pass without nuisance tripping. This is particularly valuable in applications where startup inrush currents could otherwise cause premature fuse failure. The **2AG size** (also known as 2AG or 5x20mm) is a standardized fuse format widely adopted in industrial control panels, power supplies, and automotive systems, ensuring compatibility with existing infrastructure. For applications requiring **instant fault identification**, Littelfuse offers an **indicating version** of this fuse, which visibly discolors upon opening, eliminating the need for time-consuming circuit testing. This feature is invaluable in high-reliability environments where **downtime must be minimized**, such as manufacturing plants, HVAC systems, and renewable energy installations. The indicating function reduces troubleshooting time by up to **50%**, directly improving operational efficiency and reducing maintenance costs. Professionals in **electrical engineering, panel building, and industrial maintenance** rely on Littelfuse for its **consistent quality and adherence to industry standards** (e.g., UL, CSA, and IEC certifications). The 229 Series fuses are designed to meet the demands of **IEC 60127-2** and **UL 248-14**, ensuring compliance with global safety regulations. Their **glass body construction** provides excellent visibility for inspection and adds durability in harsh environments, including those with vibration or temperature fluctuations. **Key applications** for the Littelfuse 229002P include: - **Motor protection** in pumps, conveyors, and HVAC systems - **Transformer and solenoid circuits** where inrush currents are prevalent - **Power supply units** requiring reliable overcurrent protection - **Industrial control panels** with limited space for fuse components - **Automotive and marine electrical systems** where compact, high-performance fuses are essential When selecting a time-delay fuse, engineers prioritize **interrupting rating, response time, and physical size**. The 229002P excels in all three areas, offering an **interrupting rating of 35A at 250V AC/DC**, making it suitable for both low- and medium-voltage systems. Its **axial lead and cartridge options** provide installation flexibility, whether in through-hole PCBs, fuse blocks, or DIN rail-mounted systems. Littelfuse’s reputation as a leader in circuit protection is built on **decades of innovation and reliability**. The company’s **SLO-BLO® series** has become a benchmark for time-delay fuses, trusted by OEMs and maintenance teams worldwide. For professionals seeking a **compact, high-performance fuse** that balances protection, space efficiency, and ease of maintenance, the **229002P** is an optimal choice. Whether upgrading legacy systems or designing new installations, this fuse delivers **superior performance with Littelfuse’s signature durability and safety**.
