Eaton Cartridge Fuse, 800mA Current, 250V Voltage - S501-800-R


This cartridge fuse provides fast-acting overcurrent protection for electronic and electrical assemblies operating up to 250 V. It employs a ceramic tube construction and is designed to interrupt high fault currents while offering predictable, Rapid response for sensitive circuits in industrial automation and control equipment.

Features & Benefits


• Fast-acting element delivers Rapid fault clearance for sensitive circuits
• 800 mA rating enables protection of low-current electronic loads
• High interrupting capability copes with substantial fault currents
• Silver- and nickel-plated endcaps ensure consistent contact performance
• Available with axial lead option for through-hole or wiring connections

Applications


• Suitable for control panels and distribution modules requiring 5 x 20mm fuses
• Ideal for protection of sensors and small actuators in automation systems
• Used with power supplies and converters in electronic assemblies
• Suitable for replacement of 800 mA 5 x 20mm fuse in field service

What construction materials affect thermal and electrical behaviour?


The fuse uses a ceramic tube body with silver-plated endcaps at lower currents and nickel-plated endcaps at higher currents, providing stable thermal endurance and low contact resistance under load.

How are leaded options accommodated for assembly processes?


An axial lead variant with tinned copper wire and nickel-plated brass endcaps is offered for soldering or wiring

tape-and-reel packaging provides 19.05mm lead length where specified.

What standards and approvals govern performance expectations?


The device is built to IEC 60127-2 and carries multiple agency acceptances and national approvals, reflecting adherence to recognised interrupting and safety criteria.

How does time-current performance vary across ratings?


Time-current characteristics differ by ampere rating

for this rating the fuse exhibits the short clearing times associated with F-speed fast-acting behaviour to protect downstream components.
