Fuses

Fuses are among the most commonly used electrical components, used in virtually every diy, home and industrial electronics projects. They are designed to protect electric circuits from the potentially catastrophic consequences of an overload, high current or short-circuit.

047202.5NAT1L Application Field and Working Principle

The 047202.5NAT1L is an automotive, medium-voltage fuse type designed to protect DC circuits from overloads and short-circuits. It is used exclusively in automotive systems with a rated voltage of 12VDC. Due to its environmental characteristics, this type of fuse is suitable for use in applications that have stringent requirements for temperature, vibration or humidity resistance.

The working principle of the 047202.5NAT1L involves the heat generated by an electric current flowing through the fuse element. This heat causes the element to expand and eventually to melt, breaking the electric contact and thus cutting off the power supply. The current limit of the fuse is designed considering the electric system and its components, such as switches, relays and circuits. The maximum current capacity of the 047202.5NAT1L is 12.2 Amps.

The fuse element consists of a metal strip or wire embedded in a cylindrical body of ceramic or plastic. Heat generated by the current passing through the fuse element causes the element to expand. When the current reaches the maximum capacity of the fuse, the element melts, opening the circuit and thus cutting off the power supply.

The characteristics of the 047202.5NAT1L are designed to be resistance to temperature, vibration, and humidity. This is achieved by using a special design of the fuse element and a special type of heat-resistant materials. As a result, this type of fuse is highly reliable and safe to use even under extreme environmental conditions.

The 047202.5NAT1L also provides overload protection for DC circuits. It is fitted in parallel to the power source, and when an overcurrent (or short-circuit) condition is detected, the fuse element will carry the excess current. This causes the element to expand until it melts, thus disconnecting the overcurrent.

The 047202.5NAT1L type of fuse is rated to carry up to 12.2 Amps, which is appropriate for most DC applications. Moreover, due to its special design and material construction it is highly resistant to thermal and humidity changes, making it an excellent choice for a variety of automotive applications.
