S505-3.15-R, Eaton 3.15A T Ceramic Cartridge Fuse, 5 x 20mm, Предохранитель

Eaton Bussmann Series Anti Surge (T) HBC – Ceramic Bodied, 5 x 20 mm

Eaton Bussmann anti-surge ceramic cartridge fuses are designed to prevent damage to electrical equipment. These fuses allow an electric current to flow through until the current goes over the fuse's rating then it will blow and stop the flow of electricity. This range of ceramic cartridge fuses is 5 x 20mm with a T speed rating.

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?

5x20 mm is a standard cartridge size and it measures approximately 20 mm long by 5 mm in diameter. They are popular in board and panel protection and will fit a compatible 5x20 mm fuse holder.

What Speed is it?

This particular fuse is “T” speed rated which means it is a slow acting fuse, sometimes referred to as anti-surge. It is able to tolerate higher levels for a short period, without shorting. Therefore, if a sudden change occurs, this fuse will not blow immediately. They are suitable for applications where a sudden flow of high current is required.

What voltage is it?

These cartridge fuses are available with 0.5 to 12 Amp current ratings for applications where the system voltage rating is 250 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.

Eaton Ceramic Cartridge Fuse, 3.15A, T Speed S505-3.15-R

Choose this T-speed (slow-acting) ceramic fuse from Eaton when you need to allow safe spikes in current through your circuits. Its internal fuse wire only breaks when a circuit experiences prolonged overcurrent, preventing any more flow through the circuit. Any electrical components are therefore protected against damage caused by overheating, such as cables melting or equipment fires. This fuse tolerates brief surges caused by some electrical components starting, so you can use it safely with motors without the threat of accidental tripping.

• Free from hazardous materials such as halogen and lead to minimise harm to the environment
• Standard dimensions (5mm diameter x 20mm length) for compatibility with common systems

What are the different categories of fuse speed?

There are three main types. Fast-acting (F) fuses are the most common type of cartridge fuse, used for general primary circuit protection. Very fast-acting (FF) fuses protect delicate electrical components such as diodes and transistors. Slow-acting (T) fuses, like this Eaton one, have a time-delayed feature to allow harmless inrush currents to pass without opening the fuse.
