Eaton Non-Resettable Fuse, Radial 800mA, 250V ac

This fuse provides time-delayed overcurrent protection for electronic and electrical equipment, designed for use where short transient surges must be tolerated before clearing a fault. It operates on AC supplies and is intended for Compact assemblies requiring a radial-lead protective element that withstands a wide ambient temperature range.

• 800 mA rating allows controlled protection against low-level overcurrent
• Time-delay characteristic permits acceptance of brief inrush currents
• 35A breaking capacity limits fault energy in short circuits
• 250V AC capability supports common mains applications
• Radial 1mm leads simplify PCB or through-hole mounting
• T-speed slow‑blow behaviour reduces nuisance openings during start-up

• Suitable for power supplies with high inrush currents
• Ideal for industrial control modules and automation boards
• Used with small motors and relays requiring surge tolerance
• Can be used for consumer electronics with Compact protective needs
• Used for repair and maintenance of legacy equipment in electrical systems

It functions across a wide temperature span from -40 °C up to +125 °C for reliable performance in varied environments.

Radial lead orientation with 1mm diameter and 4.3mm lead length facilitates secure through‑hole soldering and straightforward board placement.

It conforms to recognised testing and safety standards including IEC 60068-2-20, VDE and PSE for environmental and product-level assessments.

The Compact cylindrical body measures 8.5mm across with a length of 7.37mm, permitting miniaturised cartridge implementations.

The time-delay, T-speed characteristic lets brief surges pass while opening on sustained overloads, protecting downstream components.
