Eaton 25A 5ST Ceramic Cartridge Fuse, 10 x 38mm

The Eaton range of cartridge fuses is available for domestic electrical applications, from circuit breakers to plugs and sockets. These ceramic fuses are also available with an optional visual indicator.

What material are these made from?

All series of cylindrical fuse links have ceramic bodies and silverplated copper end caps.

Why choose ceramic cartridge fuse?

Ceramic and glass cartridge fuses have similar properties. The capacity of a ceramic cartridge fuse is higher than other fuses, which means that ceramic fuses can be used in circuits that have a higher current rating. They are perfect for protecting against overheating.

What size is it?

Sizes 8 x 32 mm, 10 x 38 mm, 14x51 mm & 22x58 mm in both Class gL-gG and aM are also available with a built-in striker for micro-switch operation and remote indication. Class gL-gG and aM fuse links are intended for industrial applications. All industrial fuse links are available with an operated visible fuse indicator.

What voltage is it?

This range of cylindrical cartridge fuses is available in a wide selection of physical sizes and current ratings for applications where the system voltage rating is 400, 500 and 690 Volts AC.


What is Breaking Capacity?

Breaking capacity is the level of current that the fuse can safely handle without exploding or breaking. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit.

What are cartridge fuses used for?

• For the protection of components and equipment from costly damage used by over-current
• To isolate sub-systems from the main system once a fault has appeared

What is an overcurrent?

It is a setting where a circuit experiences a current that is higher than the normal operating current.

Install this Eaton ceramic cartridge fuse to protect your applications against current overloads and overheating. It's an essential electrical safety device that breaks a circuit by melting an internal wire when a fault occurs. This prevents damage to appliances and promotes workplace safety by preventing electrical shocks and fire outbreaks. As this ceramic fuse has a 120kA breaking capacity, it offers excellent heat resistance for use with high current circuits. You can confidently use it for domestic and industrial applications.

• Compact fuse size of 10 (diameter) x 38mm (length) for compatibility with standard setups
• Ceramic body material has excellent thermal resistance for use with heavy-duty applications
• 25A current rating for use in high-powered systems

It's not possible to visually inspect a solid ceramic fuse to see if the thin fuse wire is broken or not, so you generally have to test the fuse to determine if it's still working. You can use a multimeter or a fuse indicator to do this job.
