Overview
The Littelfuse 313001 is a 3AG Slo-Blo (time-lag) cartridge fuse designed for general-purpose circuit protection in industrial and commercial applications. Rated 1 Amp 250 Volts with a 35A @ 250V AC interrupting rating, this lead-free fuse provides reliable protection for sensitive equipment. The 313 series features time-delayed protection in the overload range, which provides superior protection for inductive loads such as motors, transformers, and solenoids.
Key Features
- Glass tube body with nickel-plated brass cap and tin-plated copper leads
- 3AG indicating fuses instantly identify themselves upon opening by showing a discoloration of their glass bodies
- Lead-free, RoHS-compliant construction
- Time-delayed response ideal for motor startup inrush currents
- Widely used in industrial control panels, HVAC systems, and motor circuits
