Overview

The Littelfuse 0229.250MXSP is a 2AG Slo-Blo® Glass Indicator Fuse with a current rating of 0.250A. This fuse series, the 229, offers time-delay characteristics comparable to the 313 series 3AG fuses but occupies less than one-third the space. This compact form factor makes it ideal for applications where space is a critical constraint. The 229 series is specifically designed to provide superior protection for inductive loads, including motors, transformers, and solenoids. It is the recommended choice whenever time-delay fuses are indicated for these types of circuits. A key feature of the 0229.250MXSP is its indicating capability. The glass body of the fuse discolors upon opening, providing an immediate visual indication of a blown fuse. This eliminates the need for time-consuming circuit testing and guesswork, significantly reducing troubleshooting time and potential downtime. The design of these indicating fuses maintains the same quality performance characteristics as the standard 2AG fuse design. Manufactured in the US, the Littelfuse 0229.250MXSP ensures reliable overcurrent protection for sensitive electrical systems. Its UNSPSC code is 39121606. The 2AG Slo-Blo® Fuses are available in cartridge form or with axial leads, and the 2AG indicating fuses instantly identify themselves upon opening by showing a discoloration of their glass bodies.
