How do I identify a fuse?
Small fuses generally identify the element speed using markings such as F, M, T etc, whilst larger fuses identify the element speed using markings such as gL, gG, aM etc. Some fuses use terms such as slow acting, fast acting, motor rated etc.
What does 313 mean on a fuse?
“312” are Littelfuse fast fuses. Same as “AGC” fuses made by Bussmann. These are size 3AG — 0.25″ dia x 1.25″ long or 6.35mm x 31.75mm. “313” are Littefuse slow fuses.
What is cartridge fuse?
Definition of cartridge fuse : an electric fuse in which the link is enclosed in a cartridge.
How do you read a fuse code?
etc. As these fuses are larger in size, there is usually a lot more information printed on the fuse body. This information that is likely to be found on the fuse is summarised in the following table….Fuse Markings.
| Marking | Fuse Element Speed |
|---|---|
| M | Medium Acting (Mitteltrage) |
| T | Slow Acting (Trage) |
| TT | Very Slow Acting (Trage Trage) |
What do numbers on fuses mean?
Car fuses are color coded by amp rating. For example, a standard blue fuse has a 15-amp rating, yellow is 20 amps and green is 30. Before you buy and replace car fuses, keep in mind that the fuse panel cover often contains spare fuses and even a fuse puller.
What does 311 mean on a fuse?
3AG (311) series Normal-Blo fuses are for use in radios, amplifiers, etc. Features straight type fuse element positioned to center of fuse for easy identification of blown fuse. Voltage Rating: 32V.
Which type of fuse is used in houses?
Rewirable or Kit – Kat Type Fuses are a type of Low Voltage (LV) 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 happens if you put the wrong fuse in a plug?
If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill. Rather than risk blowing the circuit, take the car to a repair shop to determine what is causing the fuse to repeatedly blow.
What is RK5 fuse?
What is a Class RK5 Fuse,? A UL Class RK5 fuse is a current limiting, time delay fuse, that is rated to interrupt a minimum of 200,000 amps. The UL Class RK5 fuse is less expensive but less current limiting than the Class RK1 fuse,. It has a dual element, construction.
What are RK5 fuses used for?
They are current-limiting to prevent electrical damage by disconnecting circuits before they’re exposed to the full magnitude and duration of an overcurrent. UL Class RK5 fuses provide moderate current limitation for general use applications where more current-limiting RK1 fuses aren’t needed.
How do I change a cartridge fuse?
How to replace a cartridge fuse
- Buy a cartridge fuse tester so you can check which cartridge is broken.
- Turn off the main fuse in the fuse box.
- Gently remove one of the cartridges.
- Test the fuse in the cartridge fuse tester.
What size fuses for a house?
What Size Fuse Box Do I Need? The size of the fuse box needed for an individual household depends on how many circuits are used throughout the space. A general rule of thumb would be: every circuit requires 20 amps, so multiply by the number of electrical outlets (however, always consult with a qualified electrician).
What is a a fuse used for?
A fuse may be used in circuits where the fuse’s voltage rating is equal to or greater than the circuit voltage, unless otherwise stated on the fuse. For example, the FLSR_ID indicating fuse has a voltage rating of 75–600 volts. This fuse can be used on 600 volts, 480 volts, 250 volts, 125 volts, or 75 volts.
Can you use a 250V fuse on a 600V?
This fuse can be used on 600 volts, 480 volts, 250 volts, 125 volts, or 75 volts. Never use a fuse in a circuit having a higher rated voltage than the fuse. * Check specific mounting dimensions before substituting. † Check characteristics and dimensions for application before substituting.
What voltage can a fuse be used on?
voltage, unless otherwise stated on the fuse. For example, the FLSR_ID indicating fuse has a voltage rating of 75–600 volts. This fuse can be used on 600 volts, 480 volts, 250 volts, 125 volts, or 75 volts. Never use a fuse in a circuit having a higher rated voltage than the fuse.
What is the voltage rating of a FLSR ID fuse?
For example, the FLSR_ID indicating fuse has a voltage rating of 75–600 volts. This fuse can be used on 600 volts, 480 volts, 250 volts, 125 volts, or 75 volts. Never use a fuse in a circuit having a higher rated voltage than the fuse.
