Electrical fuse types chart

The low voltage fuses are divided into five types and those are of the rewirable, cartridge, drop out, striker, and switch fuses.

What are the 3 types of fuse?

Here are some of the principal types of fuse in use:

AC Fuses. AC fuses are specifically designed for use with alternating current circuits.
DC Fuses. DC fuses, by contrast, are used with direct current circuits. ...
Cylindrical Fuse Types.

What are the four types of fuses?

DC Fuses

CARTRIGE FUSES. This is the most common type of fuse.
AUTOMOTIVE FUSES. These fuses are specifically designed for automotive systems that run up to 32V and occasionally 42V. ...
RESETTABLE FUSES/POLYFUSE. Like their name suggests, these fuses are self-resetting. ...
SEMICONDUCTOR FUSES. ...
OVERVOLTAGE SUPPRESSION.

How do I know what type of fuse to use?

The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10% to the value and choosing the nearest fuse to match. This is a more precise method then just guessing should you require a 3, 5, or even 13 amp fuse.

Which type of fuse is used in houses?

Rewirable Fuses They are most commonly used in house wiring, small industries and other small current applications. Rewirable Fuses consists of two main parts: a Fuse Base, which contains the in and out terminal, and a Fuse Carrier, which holds the Fuse Element.

What is a 7 amp fuse used for?

Appliances with a small heating element (toaster, clothes iron, electric kettle) will also need a high rating fuse of 7 or 13 Amps.

What is 3 amp fuse used for?

Different types of fuses Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example: 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.

What does F on a fuse mean?

Very Fast Acting (Flink Flink) F. Fast Acting (Flink) M. Medium Acting (Mitteltrage)

What are fuse classes?

Classes of Fuses In the case of fuses, these standards have culminated in the establishment of distinct classes of low-voltage (600 volts or less) fuses, Classes RK1, RK5, G, L, T, J, H and CC being the more important.

What is the most popular type of fuse in electronics?

Rewirable Fuses The most famous kit-kat fuse (also known as rewireable fuse) mostly used in industries and home electrical wiring for small current applications in Low Voltage (LV) systems. Rewireable fuse contains 2 basic parts.

What is the difference between AC and DC fuse?

With AC circuits, the current is crossing the zero potential at 60 or 50 cycles a second. This helps in breaking the arc that forms when the fuse element melts and creates a gap. In dc circuits, the voltage does not go to a zero potential, making it more difficult to suppress the arc in the melting element's gap.

What type of fuse is High Voltage?

2.2 High Voltage Fuse They are classified into three types: Cartridge type HRC fuse, Liquid type HRC fuse, Expulsion type HRC fuse.

How do you select a fuse for a circuit?

In short, the following factors should be considered when selecting a fuse for a given system:

Normal operating current.
Operating Voltage.
Ambient Temperature.
Inrush Currents.
Maximum Fault Current.
Length of time in which the fuse must open.
Maximum allowable I ²t.

Can you replace a 3 amp fuse with a 5 amp?

A 3A fuse was used for a reason. If you replace it with a 5A fuse you will lose part of the protection the 3A fuse was intended to provide. In case of a failure of the device the fuse is suppose to protect, the result of using a larger fuse could be to damage the device to the extent that it could not be repaired.

What are 5A fuses used for?

5 amp sockets are used on the lighting circuit, meaning they are switched on and off with the light switches in the room, rather than being used like regular plug sockets. They are designed for appliances that take less than a 5 amp current, for example floor lamps, table lamps and fans.

What is an AC fuse?

What is an AC fuse? The fuse is a wire inside a glass casing, found in the disconnection box connected to your AC. The fuse is a protective measure meant to protect your air conditioner from electrical damage.

What size is the main fuse in a house?

Well, it's all about the type of appliances you have connected to your fuse box (also known as the consumer unit), and the loading this creates on your electricity system. Most modern houses have the maximum main fuse available (which is 100amp).

What amp fuse do I need?

For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted.

Can I replace a 7.5 amp fuse with a 10 amp fuse?

As far as I know, going up 2.5 or so amp (so from 7.5 to a 10) makes no difference. I've been driving with that fuse for over a year and yes, I have taken long trips with my lights on the entire time - longest being about 6 hours.

Can you use a 15 amp fuse for a 10 amp?

Just remember to put the 10 amp fuse in the correct slot and the 15 amp fuse in for the added circuit also be sure to install the add-a-circuit fuse holder in correctly or you will have power on the red add-a-circuit wire all the time with NO FUSE PROTECTION.
