Eaton S500 Series Cartridge Fuse, 250mA Current Rating, 250V AC Voltage - S500-250-R
This cartridge fuse provides fast interruption of excess current in low-voltage control and electronic circuits. Designed for panel and inline installations, it protects sensitive components by clearing faults quickly while operating within typical industrial electrical environments.
Features and Benefits:
• Fast-acting characteristic enables Rapid fault clearing to protect circuits
• Rated for 250mA continuous current to suit low-current protection needs
• 250V AC capability supports common control and signal supplies
• Glass body allows Visual inspection of the element condition
• High temperature tolerance to +125°C for elevated-heat locations
• Rated for 250mA continuous current to suit low-current protection needs
• 250V AC capability supports common control and signal supplies
• Glass body allows Visual inspection of the element condition
• High temperature tolerance to +125°C for elevated-heat locations
Applications
• Suitable for protection of automation control modules
• Ideal for safeguarding electronic measurement instruments
• Used with power supplies in industrial control panels
• Can be used for protection of relay and sensor circuits
• Ideal for safeguarding electronic measurement instruments
• Used with power supplies in industrial control panels
• Can be used for protection of relay and sensor circuits
What is the fuse element behaviour during a short circuit?
The element melts quickly under overcurrent, interrupting the fault current rapidly due to its fast-acting characteristic.
How can I visually confirm a blown device?
The transparent glass tube permits direct inspection of the fusible link to determine whether it has operated.
What operating temperatures can it withstand without degradation?
It is specified to function at ambient temperatures up to +125°C and down to -40°C for a wide thermal range of applications.
Which approvals indicate suitability for international equipment?
It carries recognised safety and conformity approvals including IEC, VDE, cURus, CSA and CCC.
How does the physical form factor affect mounting options?
The 5 x 20mm tubular format fits standard 5 x 20mm panel clips and inline fuseholders for straightforward replacement.
