Littelfuse H229001P - SLO-BLO TYPE GLASS FUSE H-PACK 1A. 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 H229001P SLO-BLO TYPE G Fuse is a high-reliance 2AG fuse engineered for space-constrained applications requiring time-delay protection. This 1A fuse delivers the same superior performance as 3AG fuses while occupying less than one-third the space, making it ideal for protecting inductive loads such as motors, transformers, and solenoids. The 229 series 2AG fuses feature a time-delay characteristic matching the 313 series 3AG fuses, ensuring reliable protection without unnecessary tripping. Available in an indicating version, these fuses provide instant visual identification upon opening by discoloring the glass body, eliminating guesswork and reducing downtime during maintenance. The compact 2AG form factor (one-third the size of 3AG) is designed for modern industrial and electronic systems where space efficiency is critical. With a glass body construction and H-pack packaging, the H229001P offers durable, high-quality overcurrent protection for sensitive electrical circuits. This fuse is manufactured in the USA by Littelfuse, a trusted leader in circuit protection solutions. The H229001P is part of the 229 series, which provides the same performance characteristics as the 313 series 3AG fuses but in a significantly smaller package. Its time-delay design ensures it can handle temporary overloads common in inductive loads without nuisance tripping, making it suitable for applications where consistent uptime is essential. The indicating version of this fuse further enhances maintenance efficiency by visually signaling an open circuit through a discolored glass body, allowing technicians to quickly locate and replace faulty fuses without extensive testing. The H-pack packaging ensures compatibility with standard fuse holders while maintaining the integrity of the fuse during handling and installation. As a space-saving alternative to larger fuses, the H229001P is particularly well-suited for compact electronic devices, automotive systems, and industrial control panels where minimizing footprint is a priority.
