Eaton S506 Series Cartridge Fuse, 8A Current Rating, 250V Voltage - S506-8-R
This cartridge fuse provides time‑delayed overcurrent protection for electrical and electronic systems. Designed for use where short‑duration inrush currents occur, it interrupts fault currents while tolerating brief surges, helping to protect components and circuits in automation, control and power distribution environments.
Features and Benefits:
• Time‑delay characteristic allows temporary inrush tolerance
• Rated current 8A for stable circuit protection
• Voltage rating 250V AC supports common mains and control systems
• Glass body permits Visual inspection of element condition
• Operates across -40°C to +125°C for wide temperature ranges
• Rated current 8A for stable circuit protection

• Glass body permits Visual inspection of element condition
• Operates across -40°C to +125°C for wide temperature ranges
Applications
• Suitable for protecting power supplies in control panels
• Ideal for safeguarding transformers and relays with inrush
• Used with PCB‑mounted fuse holders in electronic assemblies
• Can be used for motor control auxiliary circuits in industry

What physical form factor should I account for when replacing a fuse?
The unit is a 5x20mm cartridge type with a nominal length of 20mm and a 5mm diameter body that fits standard 5x20mm fuse clips.
How does the fuse behave under slow fault conditions?
It exhibits a slow‑blow or T‑speed characteristic that allows short, harmless overloads to persist while clearing sustained overcurrents.
Which approvals indicate broad international acceptability?
The component carries multiple safety approvals including UL, VDE, CSA and CCC, demonstrating compliance with several testing authorities.
What ambient extremes can the fuse withstand during operation?
It is specified to function from -40°C up to +125°C, making it suitable for a wide range of industrial environments.
