In electronics and electrical engineering, a fuse is an electrical
safety device that operates to provide overcurrent protection of an
electrical circuit. Its essential component is a metal wire or
strip that melts when too much current flows through it, thereby
stopping or interrupting the current. It is a sacrificial device;
once a fuse has operated it is an open circuit, and must be
replaced or rewired, depending on its type.
Fuses have been used as essential safety devices from the early
days of electrical engineering. Today there are thousands of
different fuse designs which have specific current and voltage
ratings, breaking capacity, and response times, depending on the
application. The time and current operating characteristics of
fuses are chosen to provide adequate protection without needless
interruption. Wiring regulations usually define a maximum fuse
current rating for particular circuits. Short circuits,
overloading, mismatched loads, or device failure are the prime or
some of the reasons for fuse operation. When a damaged live wire
makes contact with a metal case that is connected to ground, a
short circuit will form and the fuse will blow.

Selection of the Fuse and Holder Solution
The first step is to answer the following questions:
- Will the fuse need to accessible for replacement?
- How often will the fuse need to be replaced?
- Should the end customer of the appliance have access to change the
fuse?
- Should the fuse only be accessible from outside the appliance?
- How much is available to spend on safety and reliability?
Q: Are you trading company or manufacturer ?
A: We are a fuse product factory.
Q: How long is your delivery time?
A: Generally it is 3 days if the goods are in stock, 5-10 days if
the goods not in stock, according to the quantity.
Q: Do you provide samples ? is it free or extra ?
A: Yes, we could offer the samples for free charge but do not pay
the cost of freight.
Q: What are your terms of payment ?
A: 100% in advance, T/T.
