Advantages of Slow Blow Micro Fuse T3 15A 300V
Fuse is the cheapest protection device in all over the electrical circuit against the short circuit overloading of the circuit. Fuse is used in low and moderate voltage applications where the frequency operations not expected or where the use of a circuit breaker is uneconomical. It is a basic metal wire or thin strip which has the property of a low melting point which is inserted into the electrical circuit as a protective device. The fuse will protect the machine or electrical equipment against excessive currents. Here this post gives information about the advantages and disadvantages of fuse to better understand how to fuse is used in an electrical circuit.
Fuses are the cheapest form of protection.
The fuse element change very easily.
The fuse needs zero maintenance.
It affords the current limiting effect under short circuit conditions.
Its operation is completely automatic and requires less time as compared to circuit breakers and no complexity is envolved
Most of the fuses are self-protecting and also they extinguishing the arc.
When we use the small size of the fuse element impose a current limiting effect under short circuit conditions.
Its inverse time-current characteristics enable its use for overload protection.
Fuse has the ability to interrupt enormous short circuits without producing noise, flame or smoke.
Easy to removable for replacement without any damage to coming into contact with a live part.
The operation time of fuse can be much smaller than the operation of the circuit breaker. It is the primary protection device, against the short circuits.
