Eaton 630mA F Ceramic Cartridge Fuse, 5 x 20 mm

This cartridge fuse provides fast-acting overcurrent protection for low-power electronic and electrical assemblies. It is intended for use where quick interruption of fault currents is required at mains-rated voltages, and its ceramic construction supports higher breaking capacity and thermal stability compared with polymer-bodied equivalents.

• 630 mA rating for protection of low-current circuits
• Fast-blow F speed to clear short-duration faults rapidly
• Rated for 250V AC operation in typical mains applications
• Ceramic body with metal end caps for thermal resilience
• High interrupting capacity for safer fault clearing
• Available with axial lead option for through-hole mounting

• Suitable for protecting control and instrument PCB circuits
• Ideal for miniature power supplies and adapters
• Used with relay and sensor modules in automation panels
• Suitable for replacement in 5 x 20mm fuse holders and clips
• Used for protection of small transformers and coils

An axial-lead variant is offered with tinned copper wire and nickel-plated brass end caps to facilitate through-hole or wire-ended assembly.

The ceramic tube and plated end caps enable higher breaking capability and improved heat dissipation compared with non-ceramic designs.

Multiple pack formats are provided including reels with 19.05mm lead length for automated placement, and bulk cardboard or polybag options for manual feeding.

The component is designed to meet the relevant IEC specification for small-diameter fuses, ensuring consistent time to current behaviour for system design.
