Eaton S500 Series Cartridge Fuse, 2.5A Current Rating, 250V AC Voltage - S500-2.5-R
This cartridge fuse provides fast-acting overcurrent protection for electrical and electronic assemblies. It is designed for insertion into standard 5x20mm holders and safeguards circuits operating on alternating current at moderate voltages. The fuse is suited to control panels and PCB-mounted protection roles where Rapid interruption of fault currents is required.
Features and Benefits:
• Fast-acting element prevents sustained fault currents
• 2.5A rating allows precise protection for low-current circuits
• 250V AC capability supports common industrial supplies
• Glass body permits Visual fuse condition inspection
• F-speed characteristic ensures quick clearing of transient overloads
• 2.5A rating allows precise protection for low-current circuits
• 250V AC capability supports common industrial supplies
• Glass body permits Visual fuse condition inspection
• F-speed characteristic ensures quick clearing of transient overloads
Applications
• Suitable for protecting control relays and sensors in automation panels
• Ideal for safeguarding electronic modules on printed circuit boards
• Used for overcurrent protection in instrumentation and test equipment
• Can be used for replacement in Compact fuse holders in electrical enclosures

What temperature range can it tolerate during operation?
It operates across a wide thermal span from -40°C up to +125°C suitable for varied industrial environments.
Which approvals confirm its suitability for international installations?
It carries multiple approvals from recognised bodies including BSI, VDE and CSA among others indicating adherence to several national standards.
What physical form factor does it occupy for panel or PCB integration?
The device is a cylindrical glass-bodied fuse with a 5mm diameter and a 20mm overall length intended for standard 5x20mm holders.
How does the glass construction affect maintenance procedures?
The transparent housing enables Visual verification of a blown element, simplifying inspection and reducing diagnostic time.
Is the speed classification suitable for protecting sensitive electronics from surges?
The F-speed (fast blow) characteristic is tailored to interrupt sudden overloads quickly, protecting delicate components from excessive current.
