## **Description** 

ATOF[®] automotive blade fuses replaced obsolete ATO Series 257 fuses. Automakers in the United States and around the world consider ATOF[®] fuses standard equipment for protecting low-voltage circuits. 

## **Applications** 

Cars Offroad vehicles Trucks Buses SUVs Watercraft as approved by Littelfuse[®] 

## **Features & Benefits** 

Color coding shows the amperage rating for each fuse 

See-through housing makes it easy to check whether a fuse has blown 

High-contrast amperage stamp on the top of the housing aids identification 

Simple to install and remove 

Checkpoints on top make it possible to measure resistance without removing the fuse

Updated at April 28, 2026

Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
