Specialty fuses – such as the FWX-30A14F – are designed as failsafe devices that protect electrical circuits from overloads. The fuse’s operating principle and applications are important considerations when selecting the right device for a particular application.

Overview of the FWX-30A14F

The FWX-30A14F is a fast-acting, thermal-tru type fuse that can be installed into a wide range of electrical circuits. Its physical size and features make it suitable for small devices, control panels, and light and power headlamps. It is also suitable for automotive and recreational applications.

This fuse features a one-piece, solid-state construction with a glass-coated element. This specialized construction helps offer an interrupting rating of up to 10kA. It is rated for a maximum operating voltage of 600 volts AC or DC and is UL-recognized and certified to meet CSA safety standards.

FWX-30A14F Working Principle

The FWX-30A14F operates according to the thermal-tru principle. In this operating principle, the fuse element is held between two metal contacts and heated by the current flowing through it. When the current heat exceeds the melting point of the fuse element material, the element melts and creates an interruption in the circuit. This interruption prevents further circuits from being damaged by the high current.

The FWX-30A14F is designed with a patented progressive melting technology. This technology causes the fuse to slowly decline from its normal operating current to its end-of-life rating. This decline helps assure a graceful shutdown of the circuit in the event of a circuit overload.

FWX-30A14F Application Field

The FWX-30A14F is well suited for a variety of commercial, industrial and residential applications. Its size and features make it well suited for use in circuits controlled by small devices, control panels and light and power headlamps. The fuse is also useful in a variety of automotive and recreational applications.

The FWX-30A14F is specifically designed as a failsafe device to protect electrical circuits from overloads. The fuse’s working principle and applications make it a highly versatile option for a variety of special and sensitive electrical circuits. Additionally, its versatile size and features make it appropriate for both large and small circuit protection.
