Littelfuse 0229.750MXSP - 0229 SLO-BLO GLS INDICATOR M-PACK .750A. 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 0229.750MXSP is a high-performance 2AG Slo-Blo® Indicating Fuse designed to provide superior overcurrent protection for critical inductive loads. Manufactured by Littelfuse, a globally recognized leader in circuit protection, this fuse (SKU: 0229.750MXSP) offers advanced time-delay characteristics within a significantly reduced footprint compared to traditional 3AG fuses. Its compact 2AG size occupies approximately one-third the space, making it an ideal solution for space-constrained electronic and electrical systems. Engineered for demanding applications, the 229 series fuses excel in protecting inductive components such as motors, transformers, and solenoids. These components are prone to inrush currents that can cause nuisance tripping in standard fast-acting fuses. The time-delay feature of the 0229.750MXSP allows for these temporary surges without interrupting normal operation, while still providing robust protection against sustained overloads and short circuits. This fuse is the preferred choice whenever time-delay fuse protection is specified in equipment designs and maintenance procedures. A standout feature of this particular model is its indicating capability. The 0229.750MXSP incorporates a unique glass body that visibly discolors upon activation, instantly signaling that the fuse has opened. This visual indication eliminates the need for time-consuming and often frustrating circuit testing to identify a blown fuse. Technicians and engineers can quickly pinpoint the fault, reducing downtime and improving diagnostic efficiency. This feature is invaluable in complex systems where identifying a single point of failure can be challenging. Key specifications and benefits include: * **Series:** 229 Series * **Size:** 2AG (compact form factor) * **Current Rating:** 0.75 Amperes * **Material:** Glass construction for reliable performance * **Type:** Slo-Blo® (Time-Delay) for inductive loads * **Indicating Feature:** Visual discoloration for rapid fault identification * **Space Efficiency:** Occupies significantly less space than 3AG fuses * **Superior Protection:** Ideal for motors, transformers, and solenoids Littelfuse's commitment to quality and innovation is evident in the 229 series. These fuses are built to the same exacting performance standards as their larger 3AG counterparts, ensuring reliability and safety. Whether you are designing new equipment or performing maintenance on existing systems, the Littelfuse 0229.750MXSP offers a dependable and space-saving solution for your circuit protection needs. Its combination of time-delay performance, indicating functionality, and compact size makes it an essential component for modern industrial and electronic applications.
