A fuse is a piece of wire that has a lower current rating than the rest of the circuit. When power is applied to a wire, it heats up (which is why electrical items get hot with use). The fuse wire melts at a lower temperature than the rest of the circuit - meaning that it breaks before the device is damaged by high current.

What does L stand for in a fuse labeled T2AL 250V?

In a fuse labeled T2AL 250V, the "L" stands for "Low breaking capacity." This indicates that the fuse is designed to break the circuit under low fault current conditions. The "T" signifies that it is a time-delay fuse, while "2A" indicates the current rating of the fuse, which is 2 amperes. The "250V" specifies the voltage rating of the fuse.


A fuse will melt if the?

A fuse is made with the material which offers high resistivity. When a large amount of electric current passes through the fuse, heat above the melting point of fuse is produced. Hence, the fuse melts.


What does fuse rating of 5 amps mean?

A fuse rating of 5 amps means that the fuse will break the circuit if the current passing through it exceeds 5 amps. It acts as a safety measure to protect the circuit from damage due to excessive current flow.


What is a safety device that break a circuit when too much current is flowing called?

Circuit breakers are designed to automatically and manually interrupt circuits. When circuit breakers automatically actuate they are said to have 'tripped.' Also user operators can shut down circuits through individual breakers or the entire system through a master breaker.


The commonly used Safety fuse wires is made of?

Safety fuse wires are typically made of a mixture of lead and tin. This combination of metals allows the fuse wire to have a low melting point, enabling it to break and interrupt the circuit in case of overloading or short circuit.
