Eaton 5A F Glass Cartridge Fuse, 5 x 20 mm

This cartridge fuse provides fast-acting overcurrent protection for electrical and electronic systems operating on alternating current. Constructed with a tubular glass body, it interrupts fault currents rapidly to protect downstream components in control panels, instrumentation and automation equipment. The device is intended for installations requiring compact, replaceable protective elements rated for low to moderate currents.

• Fast-acting characteristic delivers Rapid fault isolation
• Rated for 5A to protect low-current circuits
• Operates at 250V AC for mains and control supply use
• Glass body allows Visual inspection of element condition
• 5mm external diameter supports Compact fuse holders

• Suitable for protecting control circuitry in automation cabinets
• Ideal for small power supplies and electronic modules
• Used with distribution boards requiring replaceable fuses
• Can be used for safeguarding sensors and signal lines
• Suitable for maintenance spares in electrical workshops

The fast-acting behaviour indicates the element melts quickly under overcurrent, limiting thermal and surge exposure to sensitive components.

The transparent tubular construction permits direct observation of the fusible link state to determine if it has opened.

A cylindrical cartridge with a 5 x 20mm envelope fits standard 5 x 20mm fuse clips and holders.

Yes, the voltage capability of 250V AC covers typical 230V single-phase systems with margin for transient conditions.
